Class CSS

java.lang.Object

javax.swing.text.html.CSS

All Implemented Interfaces:: Serializable

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.
