## 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 suppored 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
  - background-repeat
  - 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
  - border-style (only supports inset, outset and none)
  - 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.
