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.
