Properties

-ro-align-content
Aligns the content of a block-level element inside the element. The property has no effect if the height of the content is larger than the block element's height.
Value auto | start | center | end
Initial auto
Applies To block-level elements
Inherited No
auto
The content is positioned as usual inside the block.
start
Content is positioned at the top of the block.
center
Content is vertically centered inside the block.
end
Content is positioned at the bottom of the block.
background
This property is a shorthand property for setting most background properties at the same place in the style sheet. Note that only the final background layer may have a background-color.
Value [ <bg-layer> , ]* <final-bg-layer>
Initial see individual properties
Inherited No
bg-layer
<bg-image> || <position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box> || <box>
final-bg-layer
<bg-image> || <position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box> || <box> || <'background-color'>
See:
background-attachment
If background images are specified, this property specifies whether they are fixed with regard to the viewport ('fixed') or scroll along with the element ('scroll'). <attachment> = scroll | fixed | inherit
Value <attachment> [ , <attachment> ]*
Initial scroll
Inherited No
scroll
This keyword means that the background is fixed with regard to the element itself and does not scroll with its contents. (It is effectively attached to the element's border.)
fixed
This keyword means that the background is fixed with regard to the viewport. Even if an element has a scrolling mechanism, a 'fixed' background doesn't move with the element.
See:
background-clip
Determines the background painting area, which determines the area within which the background is painted.
Value border-box | padding-box | content-box [, border-box | padding-box | content-box]*
Initial border-box
Inherited No
border-box
The background is painted within (clipped to) the border box.
padding-box
The background is painted within (clipped to) the padding box.
content-box
The background is painted within (clipped to) the content box.
See:
background-color
This property sets the background color of an element. The color is drawn behind any background images.
Value <color> | transparent | inherit
Initial transparent
Inherited No
<color>
Is a CSS <color> that describes the uniform color of the background. Even if one or several background-image are defined, this color can be affect the rendering, by transparency if the images aren't opaque.
See:
Example:
h1 { background-color: #F00 } /* Sets background to red. */
background-image
This property sets the background image of an element. When setting a background image, authors should also specify a background color that will be used when the image is unavailable. When the image is available, it is rendered on top of the background color. (Thus, the color is visible in the transparent parts of the image).
Value <uri> | none [, <uri> | none]*
Initial none
Inherited No
<uri>
The format of a URI value is 'url(' followed by optional white space followed by an optional single quote (') or double quote (") character followed by the URI itself, followed by an optional single quote (') or double quote (") character followed by optional white space followed by ')'. The two quote characters must be the same.
See:
Example:
body { background-image: url("marble.png") }
p { background-image: none }
background-origin
For elements rendered as a single box, specifies the background positioning area. For elements rendered as multiple boxes (e.g. boxes on several pages), specifies which boxes 'box-decoration-break' operates on to determine the background positioning area(s).
Value border-box | padding-box | content-box | -ro-page-box | -ro-bleed-box [, border-box | padding-box | content-box | -ro-page-box | -ro-bleed-box]*
Initial padding-box
Inherited No
padding-box
The position is relative to the padding box. (For single boxes '0 0' is the upper left corner of the padding edge, '100% 100%' is the lower right corner.)
border-box
The position is relative to the border box.
content-box
The position is relative to the content box.
-ro-page-box
Only valid for background-images of pages. The background is positioned relative to the page box (including the page margins)
-ro-bleed-box
Only valid for background-images of pages. The background is positioned relative to the bleed box.
See:
background-position
If a background image has been specified, this property specifies its initial position. If only one value is specified, the second value is assumed to be 'center'. If at least one value is not a keyword, then the first value represents the horizontal position and the second represents the vertical position. Negative <percentage> and <length> values are allowed. <position> = [ [ left | center | right | top | bottom | <percentage> | <length> ] | [ left | center | right | <percentage> | <length> ] [ top | center | bottom | <percentage> | <length> ] | [ center | [ left | right ] [ <percentage> | <length> ]? ] && [ center | [ top | bottom ] [ <percentage> | <length> ]? ] ] | inherit
Value <position> [ , <position> ]*
Initial 0% 0%
Inherited No
<percentage>
A percentage X aligns the point X% across (for horizontal) or down (for vertical) the image with the point X% across (for horizontal) or down (for vertical) the element's padding box. For example, with a value pair of '0% 0%',the upper left corner of the image is aligned with the upper left corner of the padding box. A value pair of '100% 100%' places the lower right corner of the image in the lower right corner of the padding box. With a value pair of '14% 84%', the point 14% across and 84% down the image is to be placed at the point 14% across and 84% down the padding box.
<length>
A length L aligns the top left corner of the image a distance L to the right of (for horizontal) or below (for vertical) the top left corner of the element's padding box. For example, with a value pair of '2cm 1cm', the upper left corner of the image is placed 2cm to the right and 1cm below the upper left corner of the padding box.
top
Equivalent to '0%' for the vertical position.
right
Equivalent to '100%' for the horizontal position.
bottom
Equivalent to '100%' for the vertical position.
left
Equivalent to '0%' for the horizontal position.
center
Equivalent to '50%' for the horizontal position if it is not otherwise given, or '50%' for the vertical position if it is.
See:
background-repeat
If a background image is specified, this property specifies whether the image is repeated (tiled), and how. All tiling covers the content, padding and border areas of a box. <repeat-style> = repeat-x | repeat-y | [repeat | space | round | no-repeat]{1,2} If two keywords are used, the first defines the horizontal repeat style, the second the vertical one.
Value <repeat-style> [ , <repeat-style> ]*
Initial repeat
Inherited No
repeat
The image is repeated both horizontally and vertically. Or for one direction if used together with another keyword.
repeat-x
The image is repeated horizontally only.
repeat-y
The image is repeated vertically only.
no-repeat
The image is not repeated: only one copy of the image is drawn.
space
The image is repeated as often as possible without clipping. The remaining space is then distributed between the images.
round
The image is repeated as often as possible without clipping. Then the remaining space is filled by scaling the images until they fit.
See:
background-size
Specifies the size of the background images. <bg-size> = [ <length> | <percentage> | auto ]{1,2} | cover | contain
Value <bg-size> [ , <bg-size> ]*
Initial auto
Inherited No
[ <length> | <percentage> | auto ]{1,2}
The first value gives the width of the corresponding image, the second value its height. If only one value is given the second is assumed to be 'auto'. A percentage is relative to the background positioning area. An 'auto' value for one dimension is resolved by using the image's intrinsic ratio and the size of the other dimension, or failing that, using the image's intrinsic size, or failing that, treating it as 100%. If both values are 'auto' then the intrinsic width and/or height of the image should be used, if any, the missing dimension (if any) behaving as 'auto' as described above. If the image has neither an intrinsic width nor an intrinsic height, its size is determined as for 'contain'. Negative values are not allowed.
cover
Scales the image so that it completely covers the area, without changing its aspect ratio.
contain
Scales the image so that it completely fits in the area, without changing its aspect ratio.
See:
border
This property is a shorthand property for setting the same width, color, and style for all four borders of a box.
Value <line-width> || <line-style> || <color>
Initial see individual properties
Inherited No
See:
border-bottom-left-radius border-bottom-right-radius border-top-left-radius border-top-right-radius
The two length or percentage values of the 'border-*-radius' properties define the radii of a quarter ellipse that defines the shape of the corner of the outer border edge. The first value is the horizontal radius, the second the vertical radius. If the second value is omitted it is copied from the first. If either length is zero, the corner is square, not rounded. Percentages for the horizontal radius refer to the width of the border box, whereas percentages for the vertical radius refer to the height of the border box. Negative values are not allowed.
Value [<length> | <percentage>]{1,2}
Initial 0
Applies To all elements (but see prose)
Inherited No
See:
border-collapse
This property selects a table's border model. The value 'separate' selects the separated borders border model. The value 'collapse' selects the collapsing borders model.
Value collapse | separate | inherit
Initial separate
Applies To 'table' and 'inline-table' elements
Inherited Yes
See:
border-color
The 'border-color' property sets the color of the four borders. The 'border-color' property can have from one to four component values, and the values are set on the different sides as for 'border-width'.

BiDi text direction dependent alternatives for border-top-width, border-bottom-width, border-left-width and border-right-width.
Value <border-width> | inherit
Initial medium
Inherited No
See:
border-radius
The 'border-radius' shorthand sets all four 'border-*-radius' properties. If values are given before and after the slash, then the values before the slash set the horizontal radius and the values after the slash set the vertical radius. If there is no slash, then the values set both radii equally. The four values for each radii are given in the order top-left, top-right, bottom-right, bottom-left. If bottom-left is omitted it is the same as top-right. If bottom-right is omitted it is the same as top-left. If top-right is omitted it is the same as top-left.
Value [ <length> | <percentage> ]{1,4} [ / [ <length> | <percentage> ]{1,4} ]?
Initial see individual properties
Applies To all elements (but see prose)
Inherited No
See:
border-spacing
The lengths specify the distance that separates adjoining cell borders. If one length is specified, it gives both the horizontal and vertical spacing. If two are specified, the first gives the horizontal spacing and the second the vertical spacing. Lengths may not be negative. The distance between the table border and the borders of the cells on the edge of the table is the table's padding for that side, plus the relevant border spacing distance. For example, on the right hand side, the distance is padding-right + horizontal border-spacing.
Value <length> <length>? | inherit
Initial 0
Applies To 'table' and 'inline-table' elements
Inherited Yes
See:
border-style
The 'border-style' property sets the style of the four borders. It can have from one to four component values, and the values are set on the different sides as for 'border-width'.

The border is transparent (though it may have width).
See:
border-top-style border-right-style border-bottom-style border-left-style
The border style properties specify the line style of a box's border (solid, double, dashed, etc.). The properties defined in this section refer to the <border-style> value type, which may take one of the following values:
Value <border-style> | inherit
Initial none
Inherited No
none
No border; the computed border width is zero.
hidden
Same as 'none', except in terms of border conflict resolution for table elements.
dotted
The border is a series of dots.
dashed
The border is a series of short line segments.
solid
The border is a single line segment.
double
The border is two solid lines. The sum of the two lines and the space between them equals the value of 'border-width'.
groove
The border looks as though it were carved into the canvas.
ridge
The opposite of 'groove': the border looks as though it were coming out of the canvas.
inset
The border makes the box look as though it were embedded in the canvas.
outset
The opposite of 'inset': the border makes the box look as though it were coming out of the canvas.
See:
border-top-width border-right-width border-bottom-width border-left-width
The border width properties specify the width of the border area. The properties defined in this section refer to the <border-width> value type, which may take one of the following values:
Value <border-width> | inherit
Initial medium
Inherited No
thin
A thin border.
medium
A medium border.
thick
A thick border.

See:
border-width
This property is a shorthand property for setting 'border-top-width', 'border-right-width', 'border-bottom-width', and 'border-left-width' at the same place in the style sheet. If there is only one component value, it applies to all sides. If there are two values, the top and bottom borders are set to the first value and the right and left are set to the second. If there are three values, the top is set to the first value, the left and right are set to the second, and the bottom is set to the third. If there are four values, they apply to the top, right, bottom, and left, respectively.
Value <border-width>{1,4} | inherit
Initial see individual properties
Inherited No
See:
bottom
Like 'top', but specifies how far a box's bottom margin edge is offset above the bottom of the box's containing block. For relatively positioned boxes, the offset is with respect to the bottom edge of the box itself.
Value <length> | <percentage> | auto | inherit
Initial auto
Applies To positioned elements
Inherited No
<length>
The offset is a fixed distance from the reference edge. Negative values are allowed.
<percentage>
The offset is a percentage of the containing block's height. Negative values are allowed.
auto
For non-replaced elements, the effect of this value depends on which of related properties have the value 'auto' as well. For replaced elements, the effect of this value depends on the intrinsic dimensions of the replaced content.
See:
box-decoration-break
When a block is split, this property determines whether margins, borders and paddings wrap the edges of the split box or if they should be "sliced". If a block has a background, this property determines whether the background is "sliced".
Value slice | clone
Initial clone
Inherited No
clone
Each box fragment is rendered individually. Margins, borders, and paddings wrap around all edges of the box. Backgrounds are restart in each fragment.
slice
The box fragments are rendered as if they were sliced. Background images are continued in the next fragment, margins, border and paddings are removed "between" the fragments.
See:
box-sizing
Defines which box is used to calculate the widths and heights of elements.
Value content-box | border-box
Initial content-box
Inherited No
content-box
This is the behavior as specified by CSS2.1. The width and height properties apply to the width and height of the content box of the element. The padding and border of the element are laid out and drawn outside the specified width and height.
border-box
Width and height properties on this element determine the border box of the element. That means that any padding or border specified on the element is laid out and drawn inside this specified width and height.
See:

Applies To non-replaced block-level elements (except table elements), table cells, and inline-block elements
Inherited No
auto
means that the number of columns will be determined by other properties (e.g., 'column-width', if it has a non-auto value).
<integer>
describes the optimal number of columns into which the content of the element will be flowed. Values must be greater than 0. If both 'column-width' and 'column-count' have non-auto values, the integer value describes the maximum number of columns.
See:
column-fill
In continuous media, this property will only be consulted if the length of columns has been constrained. Otherwise, columns will automatically be balanced.
Value balance | auto
Initial balance
Applies To multicol elements
Inherited No
balance
Balance content equally between columns, if possible.
auto
Fills columns sequentially.
See:
column-gap
The 'column-gap' property sets the gap between columns. If there is a column rule between columns, it will appear in the middle of the gap.

Value <border-style> | none
Initial none
Applies To multicol elements
Inherited No
See:
column-rule-width
This property sets the width of the rule between columns. Negative values are not allowed.
Value <border-width> | <percentage> | none
Initial medium
Applies To multicol elements
Inherited No
See:

Value none | all
Initial none
Applies To block-level elements, except floating and absolutely positioned elements
Inherited No
none
The element does not span multiple columns.

See:
column-width
This property describes the width of columns in multicol elements.
Value <length> | auto
Initial auto
Applies To non-replaced block-level elements (except table elements), table cells, and inline-block elements
Inherited No
auto
means that the column width will be determined by other properties (e.g., 'column-count', if it has a non-auto value).
<length>

This is a shorthand property for setting 'column-width' and 'column-count'. Omitted values are set to their initial values.
Value <integer> | <length> | auto
Initial see individual properties
Applies To non-replaced block-level elements (except table elements), table cells, and inline-block elements
Inherited No
content
This property is used with the :before and :after pseudo-elements to generate content in a document.
Value normal | none | [ <string> | <counter> | attr(<identifier>) | <target-counter> | <target-text> | <named-string> | <leader> ]+ | <running-element> | inherit
Initial normal
Applies To :before and :after pseudo-elements
Inherited No
none
The pseudo-element is not generated.
normal
Computes to 'none' for the :before and :after pseudo-elements.
<string>
Text content.
<counter>
Counters may be specified with two different functions: 'counter()' or 'counters()'.
attr(<attribute>)
This function returns as a string the value of attribute <attribute> for the subject of the selector.
<target-counter>
Target counters may be specified with two different functions: 'target-counter()' or 'target-counters()'.
<target-text>
Target text may be specified with the function: 'target-text()'.
<named-string>
Named strings may be specified with the function: 'string()'. The string function has two arguments. The name of the named string as identifier and the location on the page (which is optional).
<leader>
Leaders may be specified with the function: 'leader()'.
<running-element>
Running Elements may be specified with the function: 'element()' from a position property. The element function has two arguments. The name of the running element as identifier and the location on the page (which is optional).
See:
counter-increment
The 'counter-increment' property accepts one or more names of counters (identifiers), each one optionally followed by an integer. The integer indicates by how much the counter is incremented for every occurrence of the element. The default increment is 1. Zero and negative integers are allowed.
Value none | [ <identifier> <integer>? ]+ | inherit
Initial none
Inherited No
See:
counter-reset
The 'counter-reset' property contains a list of one or more names of counters, each one optionally followed by an integer. The integer gives the value that the counter is set to on each occurrence of the element. The default is 0.
Value none | [ <identifier> <integer>? ]+ | inherit
Initial none
Inherited No
See:
-ro-counter-set
The '-ro-counter-set' property contains a list of one or more names of counters, each one optionally followed by an integer. The integer gives the value that the counter is set to on each occurrence of the element. The default is 0. The difference to the 'counter-reset' property is, that '-ro-counter-set' does not create a new instance of a counter if an existing counter is present. This allows '-ro-counter-set' to reset an existing counter from anywhere inside the document.
Value none | [ <identifier> <integer>? ]+ | inherit
Initial none
Inherited No
display
The computed value is the same as the specified value, except for positioned and floating elements (see Relationships between 'display', 'position', and 'float') and for the root element. For the root element, the computed value is changed as described in the section on the relationships between 'display', 'position', and 'float'. Note that although the initial value of 'display' is 'inline', rules in the user agent's default style sheet may override this value. See the sample style sheet for HTML 4 in the appendix.
Value inline | block | list-item | inline-block | table | inline-table | table-row-group | table-row | table-cell | none | inherit
Initial inline
Inherited No
block
This value causes an element to generate a block box.
inline-block
This value causes an element to generate an inline-level block container. The inside of an inline-block is formatted as a block box, and the element itself is formatted as an atomic inline-level box.
inline
This value causes an element to generate one or more inline boxes.
list-item
This value causes an element (e.g., LI in HTML) to generate a principal block box and a marker box. For information about lists and examples of list formatting, please consult the section on lists.
none
This value causes an element to not appear in the formatting structure (i.e., in visual media the element generates no boxes and has no effect on layout). Descendant elements do not generate any boxes either; the element and its content are removed from the formatting structure entirely. This behavior cannot be overridden by setting the 'display' property on the descendants. Please note that a display of 'none' does not create an invisible box; it creates no box at all. CSS includes mechanisms that enable an element to generate boxes in the formatting structure that affect formatting but are not visible themselves. Please consult the section on visibility for details.
table, inline-table, table-row-group, table-column, table-column-group, table-header-group, table-footer-group, table-row, table-cell, and table-caption
These values cause an element to behave like a table element (subject to restrictions described in the chapter on tables).

This property defines whether an element and all its descendants are editable, not editable or not deletable. How this property is evaluated depends on the operation. If an operation is not a deletion operation then no-deletion is equivalent to true. If an operation is a deletion operation then no-deletion is equivalent to false.
Value true | false | no-deletion
Initial true
Inherited Yes
true
Editing is allowed.
false
Editing is prevented.
no-deletion
Editing is allowed unless it is a deletion.
See:
-ro-editable-inside
This property describes whether all descendants of an element are editable, not editable or not deletable. How this property is evaluated depends on the operation. If an operation is not a deletion operation then no-deletion is equivalent to true. If an operation is a deletion operation then no-deletion is equivalent to false.
Value true | false | no-deletion
Initial true
Inherited Yes
true
Editing is allowed.
false
Editing is prevented.
no-deletion
Editing is allowed unless it is a deletion.
See:
empty-cells
In the separated borders model, this property controls the rendering of borders and backgrounds around cells that have no visible content. Empty cells and cells with the 'visibility' property set to 'hidden' are considered to have no visible content.
Value show | hide | inherit
Initial show
Applies To 'table-cell' elements
Inherited Yes
show
When this property has the value 'show', borders and backgrounds are drawn around/behind empty cells (like normal cells).
hide
A value of 'hide' means that no borders or backgrounds are drawn around/behind empty cells. Furthermore, if all the cells in a row have a value of 'hide' and have no visible content, then the row has zero height and there is vertical border-spacing on only one side of the row.
See:
float
This property specifies whether a box should float to the left, right, or not at all. It may be set for any element, but only applies to elements that generate boxes that are not absolutely positioned.
Value left | right | -ro-inline-start | -ro-inline-end | footnote | none | inherit
Initial none
Inherited No
left
The element generates a block box that is floated to the left. Content flows on the right side of the box, starting at the top (subject to the 'clear' property).
right
Similar to 'left', except the box is floated to the right, and content flows on the left side of the box, starting at the top.
-ro-inline-start
BiDi text direction dependent alternative for 'left' or 'right'.
-ro-inline-end
BiDi text direction dependent alternative for 'right' or 'left'.
none
The box is not floated.
See:
-ro-flow-from
The 'flow-from' property makes a block container a region and associates it with a named flow.
Value none | <identifier> | inherit
Initial
Applies To Non-replaced block containers.
Inherited No
none
The block container is not a CSS Region.
<identifier>
The block container becomes a CSS Region, and is ordered in a region chain according to its document order.
See:
-ro-flow-into
The 'flow-into' property can place an element or its contents into a named flow. Content that belongs to the same flow is laid out in regions associated with that flow. The 'flow-into' property neither affects the CSS cascade and inheritance nor the DOM position of an element or its contents. A named flow needs to be associated with one or more regions to be displayed.
Value none | <identifier> [element|content]?
Initial none
Applies To All elements, but not pseudo-elements such as ::first-line, ::first-letter, ::before or ::after.
Inherited No
none
The element is not moved to a named flow and normal CSS processing takes place.
<identifier>
If the keyword 'element' or neither keyword is present, the element is taken out of its parent's flow and placed into the named flow '<identifier>'. If the keyword 'content' is present, then only the element's contents is placed into the named flow. The values 'none', 'inherit', 'default', 'auto' and 'initial' are invalid flow names.
See:
font
The 'font' property is, except as described below, a shorthand property for setting 'font-style', 'font-variant', 'font-weight', 'font-size', 'line-height' and 'font-family' at the same place in the style sheet. The syntax of this property is based on a traditional typographical shorthand notation to set multiple properties related to fonts. All font-related properties are first reset to their initial values, including those listed in the preceding paragraph. Then, those properties that are given explicit values in the 'font' shorthand are set to those values.
Value [ [ 'font-style' || 'font-weight' ]? 'font-size' [ / 'line-height' ]? 'font-family' ] | inherit
Initial see individual properties
Inherited Yes
See:
font-family
The property value is a prioritized list of font family names and/or generic family names. Unlike most other CSS properties, component values are separated by a comma to indicate that they are alternatives.
Value [[ <family-name> | <generic-family> ] [, <family-name>| <generic-family>]* ] | inherit
Initial depends on user agent
Inherited Yes
<family-name>
The name of a font family of choice.
<generic-family>
The following generic families are defined: 'serif' (e.g., Times) 'sans-serif' (e.g., Helvetica) 'cursive' (e.g., Zapf-Chancery) 'fantasy' (e.g., Western) 'monospace' (e.g., Courier) Style sheet designers are encouraged to offer a generic font family as a last alternative. Generic font family names are keywords and must NOT be quoted.
See:
font-size
The font size corresponds to the em square, a concept used in typography. Note that certain glyphs may bleed outside their em squares.
Value <absolute-size> | <relative-size> | <length> | <percentage> | inherit
Initial medium
Inherited Yes
<absolute-size>
An <absolute-size> keyword is an index to a table of font sizes computed and kept by the UA. Possible values are: [ xx-small | x-small | small | medium | large | x-large | xx-large ]
<relative-size>
A <relative-size> keyword is interpreted relative to the table of font sizes and the font size of the parent element. Possible values are: [ larger | smaller ]. For example, if the parent element has a font size of 'medium', a value of 'larger' will make the font size of the current element be 'large'.
See:
font-style
The 'font-style' property selects between normal (sometimes referred to as "roman" or "upright"), italic and oblique faces within a font family.
Value normal | italic | oblique | inherit
Initial normal
Inherited Yes
See:
font-variant
Another type of variation within a font family is the small-caps. In a small-caps font the lower case letters look similar to the uppercase ones, but in a smaller size and with slightly different proportions. The 'font-variant' property selects that font.
Value normal | small-caps | inherit
Initial normal
Inherited Yes
See:
font-weight
The 'font-weight' property selects the weight of the font. The values '100' to '900' form an ordered sequence, where each number indicates a weight that is at least as dark as its predecessor. The keyword 'normal' is synonymous with '400', and 'bold' is synonymous with '700'. The 'bolder' and 'lighter' values select font weights that are relative to the weight inherited from the parent.
Value normal | bold | bolder | lighter | 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 | inherit
Initial normal
Inherited Yes
See:
height
This property specifies the content height of boxes. This property does not apply to non-replaced inline elements. Negative values for 'height' are illegal.
Value <length> | <percentage> | auto | inherit
Initial auto
Applies To all elements but non-replaced inline elements, table columns, and column groups
Inherited No
<length>
Specifies the height of the content area using a length value.
<percentage>
Specifies a percentage height. The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'. A percentage height on the root element is relative to the initial containing block.
auto
The height depends on the values of other properties.
See:
hyphenate-after
This property specifies the minimum number of characters in a hyphenated word after the hyphenation character. The 'auto' value means that the UA chooses a value that adapts to the current layout.
Value <integer> | auto
Initial auto
Inherited Yes
See:
hyphenate-before
This property specifies the minimum number of characters in a hyphenated word before the hyphenation character. The 'auto' value means that the UA chooses a value that adapts to the current layout.
Value <integer> | auto
Initial auto
Inherited Yes
See:
hyphenate-character
This property specifies a string that is shown when a hyphenate-break occurs. The 'auto' value means that the user agent should find an appropriate value.
Value <string> | auto
Initial auto
Inherited Yes
See:
hyphens
This property controls whether hyphenation is allowed to create more soft wrap opportunities within a line of text.
Value none | manual | auto
Initial manual
Inherited Yes
none
Words are not hyphenated, even if characters inside the word explicitly define hyphenation opportunities.
manual
Words are only hyphenated where there are characters inside the word that explicitly suggest hyphenation opportunities.
auto
Words may be broken at appropriate hyphenation points either as determined by hyphenation characters inside the word or as determined automatically by a language-appropriate hyphenation resource. Conditional hyphenation characters inside a word, if present, take priority over automatic resources when determining hyphenation opportunities within the word.
See:
left
Like 'top', but specifies how far a box's left margin edge is offset to the right of the left edge of the box's containing block. For relatively positioned boxes, the offset is with respect to the left edge of the box itself.
Value <length> | <percentage> | auto | inherit
Initial auto
Applies To positioned elements
Inherited No
<length>
The offset is a fixed distance from the reference edge. Negative values are allowed.
<percentage>
The offset is a percentage of the containing block's width. Negative values are allowed.
auto
For non-replaced elements, the effect of this value depends on which of related properties have the value 'auto' as well. For replaced elements, the effect of this value depends on the intrinsic dimensions of the replaced content.
See:
letter-spacing
This property specifies spacing behavior between text characters.
Value normal | <length> | inherit
Initial normal
Inherited Yes
normal
The spacing is the normal spacing for the current font. This value allows the user agent to alter the space between characters in order to justify text.
<length>
This value indicates inter-character space in addition to the default space between characters.
See:
-ro-line-grid
Specifies whether this box creates a new baseline grid for its descendants or uses the same baseline grid as its parent.
Value match-parent | create
Initial match-parent
Applies To block containers
Inherited No
match-parent
Box assumes the line grid of its parent.
create
Box creates a new line grid using its own font and line layout settings.
See:
line-height
On a block container element whose content is composed of inline-level elements, 'line-height' specifies the minimal height of line boxes within the element. The minimum height consists of a minimum height above the baseline and a minimum depth below it, exactly as if each line box starts with a zero-width inline box with the element's font and line height properties.
Value normal | <number> | <length> | <percentage> | inherit
Initial normal
Inherited Yes
normal
Tells user agents to set the used value to a "reasonable" value based on the font of the element. The value has the same meaning as <number>. The computed value is 'normal'.
<length>
The specified length is used in the calculation of the line box height. Negative values are illegal.
<number>
The used value of the property is this number multiplied by the element's font size. Negative values are illegal. The computed value is the same as the specified value.
<percentage>
The computed value of the property is this percentage multiplied by the element's computed font size. Negative values are illegal.
See:
-ro-line-snap
This property applies to all the line boxes directly contained by the element, and, when not none, causes each line box to shift until it snaps to the line grid specified by line-grid.
Value none | baseline | contain
Initial none
Inherited Yes
none
Line boxes do not snap to the grid; they stack normally.
baseline
The baseline snaps to the line grid applied to the element.
contain
Two baselines are used to align the line box: the line box is snapped so that its central baseline is centered between two of the line grid's baselines.
See:
list-style
The 'list-style' property is a shorthand notation for setting the three properties 'list-style-type', 'list-style-image', and 'list-style-position' at the same place in the style sheet.
Value [ 'list-style-type' || 'list-style-position' || 'list-style-image' ] | inherit

See:
list-style-position
This property specifies the position of the marker box with respect to the principal block box.
Value inside | outside | inherit
Initial outside
Applies To elements with 'display: list-item'
Inherited Yes
outside
The marker box is outside the principal block box. The position of the list-item marker adjacent to floats is undefined in CSS 2.1. CSS 2.1 does not specify the precise location of the marker box or its position in the painting order, but does require that for list items whose 'direction' property is 'ltr' the marker box be on the left side of the content and for elements whose 'direction' property is 'rtl' the marker box be on the right side of the content. The marker box is fixed with respect to the principal block box's border and does not scroll with the principal block box's content.
inside
The marker box is placed as the first inline box in the principal block box, before the element's content and before any :before pseudo-elements.
See:
list-style-type
This property specifies appearance of the list item marker if 'list-style-image' has the value 'none' or if the image pointed to by the URI cannot be displayed. The value 'none' specifies no marker, otherwise there are three types of marker: glyphs, numbering systems, and alphabetic systems. Glyphs are specified with disc, circle, and square.
Value <counter-style> | none | inherit
Initial disc
Applies To elements with 'display: list-item'
Inherited Yes
<counter-style>
The list item marker is formatted according to the given counter style. Unordered types are: box, check, circle, diamond, disc, dash, square. Ordered types are for example lower-alpha, lower-greek or upper-roman.
See:
margin
The 'margin' property is a shorthand property for setting 'margin-top', 'margin-right', 'margin-bottom', and 'margin-left' at the same place in the style sheet. If there is only one component value, it applies to all sides. If there are two values, the top and bottom margins are set to the first value and the right and left margins are set to the second. If there are three values, the top is set to the first value, the left and right are set to the second, and the bottom is set to the third. If there are four values, they apply to the top, right, bottom, and left, respectively.
Value <margin-width>{1,4} | inherit
Initial see individual properties
Applies To all elements except elements with table display types other than table-caption, table and inline-table
Inherited No

Initial none
Applies To all elements but non-replaced inline elements, table columns, and column groups
Inherited No
<length>
Specifies a fixed maximum computed height.
<percentage>
Specifies a percentage for determining the used value. The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the percentage value is treated as 'none'.
none
No limit on the height of the box.
See:
max-width
This property allows authors to constrain content widths to a maximum.
Value <length> | <percentage> | none | inherit
Initial none
Applies To all elements but non-replaced inline elements, table rows, and row groups
Inherited No
<length>
Specifies a fixed maximum used width.
<percentage>
Specifies a percentage for determining the used value. The percentage is calculated with respect to the width of the generated box's containing block. If the containing block's width is negative, the used value is zero. If the containing block's width depends on this element's width, then the resulting layout is undefined in CSS 2.1.
none
No limit on the width of the box.
See:
min-height
This property allows authors to set a minimum box height.
Value <length> | <percentage> | inherit
Initial 0
Applies To all elements but non-replaced inline elements, table columns, and column groups
Inherited No
<length>
Specifies a fixed minimum computed height.
<percentage>
Specifies a percentage for determining the used value. The percentage is calculated with respect to the height of the generated box's containing block.

portrait
Specifies that the page's content be printed in portrait orientation. The shorter sides of the page box are horizontal. If a '<page-size>' is not specified, the size of the page sheet is chosen by the UA.
<length>
The page box will be set to the given absolute dimension(s). If only one length value is specified, it sets both the width and height of the page box (i.e., the box is a square). If two length values are specified, the first establishes the page box width, and the second the page box height. Values in units of 'em' and 'ex' refer to the page context's font. Negative lengths are illegal.

The optional property -ro-style-template-context describes what context the Style Template may be used in. A context limits the Style Template to be used only on elements whose value of the -ro-context property equals one of those defined with this property.
Value document | none | [<string>] | inherit
Initial document
Applies To depends on type, see -ro-style-template
Inherited No
document
The Style Template may be used throughout the whole document. This value is used by default.
none
The Style Template may not be used in the entire document. This option allows disabling the Style Template permanently.
<string>
The name of a context the Style Template may be used in. This context name refers to the context names defined via -ro-context property.
See:
-ro-style-template-group
The optional property -ro-style-template-group describes which group the Style Template is in. A group makes its Style Template members mutual exclusive, meaning only one of the group's members can be applied. Some things need to be considered on grouping Style Templates: All Style Templates should have the same element type. Actions will be created for those Style Templates only whose element type belongs to the majority of present element types in that group. Style Templates with same selector should not be inside the same group. If inside a group the selector of one Style Template matches another Style Template's selector the selected state of one of both Style Template's actions will be wrong. Even though the Style Template is applied one of both actions won't be selected. It is a restriction that comes with the design principle of mutual exclusive members of the Style Template group.
Value template-name | <string> | inherit
Initial template-name
Applies To depends on element type, see -ro-style-template
Inherited No
template-name
The group for the Style Template is named after the Style Template itself.

See:
-ro-style-template-not-context
The optional property -ro-style-template-not-context describes what context the Style Template may not be used in. This definition limits the Style Template to be used everywhere else but on elements whose value of the -ro-context property equals one of those defined with this property. Note: This property will be ignored if -ro-style-template-context is defined.
Value none | document | [<string>] | inherit
Initial none
Applies To depends on type, see -ro-style-template
Inherited No
none
The Style Template may be used in the entire document.
document
The Style Template may not be used in the entire document. This option allows disabling the Style Template permanently.
<string>
The name of a context the Style Template may not be used in. This context name refers to the context names defined via -ro-context property.
See:
-ro-style-template-toggle-id -ro-style-template-setter-id
The optional properties -ro-style-template-toggle-id and -ro-style-template-setter-id specify the ID of the Java actions created from this Style Template. The -ro-style-template-toggle-id stands for toggle actions created from the Style Template while -ro-style-template-setter-id stands for setter actions. If one of these properties is not defined the related action's ID is generated and may change when Style Templates are (re)loaded. With a fixed ID an action created from a Style Template can be made part of a fixed user interface that retrieves the action by ID rather than via the Java StyleTemplate object.
Value none | <string> | inherit
Initial none
Applies To depends on type, see -ro-style-template
Inherited No
none
No ID is defined for the Style Template.
<string>
The ID value the action created from the Style Template will receive.
