* Value: < absolute-size > | < relative-size > | < length > | < percentage > | inherit
|
|
|
* Initial: medium
|
|
|
* Applies to: text content elements
|
|
|
* Inherited: yes, the computed value is inherited
|
|
|
* Percentages: refer to parent element's font size
|
|
|
* Media: visual
|
|
|
* Animatable: yes
|
|
|
* <p>
|
|
|
* This property refers to the size of the font from baseline to
|
|
|
* baseline when multiple lines of text are set solid in a multiline
|
|
|
* layout environment.
|
|
|
* <p>
|
|
|
* For SVG, if a < length > is provided without a unit identifier
|
|
|
* (e.g., an unqualified number such as 128), the SVG user agent
|
|
|
* processes the < length > as a height value in the current user
|
|
|
* coordinate system.
|
|
|
* <p>
|
|
|
* If a < length > is provided with one of the unit identifiers
|
|
|
* (e.g., 12pt or 10%), then the SVG user agent converts the
|
|
|
* < length > into a corresponding value in the current user
|
|
|
* coordinate system by applying the rules described in Units.
|
|
|
* <p>
|
|
|
* Except for any additional information provided in this specification,
|
|
|
* the normative definition of the property is in CSS2 ([CSS2], section 15.2.4).
