All Implemented Interfaces:

public class CSS extends Object implements Serializable
Defines a set of CSS attributes as a typesafe enumeration. The HTML View implementations use CSS attributes to determine how they will render. This also defines methods to map between CSS/HTML/StyleConstants. Any shorthand properties, such as font, are mapped to the intrinsic properties.

The following describes the CSS properties that are supported by the rendering engine:

  • font-family
  • font-style
  • font-size (supports relative units)
  • font-weight
  • font
  • color
  • background-color (with the exception of transparent)
  • background-image
  • background-repeat
  • background-position
  • background
  • text-decoration (with the exception of blink and overline)
  • vertical-align (only sup and super)
  • text-align (justify is treated as center)
  • margin-top
  • margin-right
  • margin-bottom
  • margin-left
  • margin
  • padding-top
  • padding-right
  • padding-bottom
  • padding-left
  • padding
  • border-top-style
  • border-right-style
  • border-bottom-style
  • border-left-style
  • border-style (only supports inset, outset and none)
  • border-top-color
  • border-right-color
  • border-bottom-color
  • border-left-color
  • border-color
  • list-style-image
  • list-style-type
  • list-style-position
The following are modeled, but currently not rendered.
  • font-variant
  • background-attachment (background always treated as scroll)
  • word-spacing
  • letter-spacing
  • text-indent
  • text-transform
  • line-height
  • border-top-width (this is used to indicate if a border should be used)
  • border-right-width
  • border-bottom-width
  • border-left-width
  • border-width
  • border-top
  • border-right
  • border-bottom
  • border-left
  • border
  • width
  • height
  • float
  • clear
  • display
  • white-space
  • list-style

Note: for the time being we do not fully support relative units, unless noted, so that p { margin-top: 10% } will be treated as if no margin-top was specified.
