public class CssBackground
extends CssProperty
implements CssOperator, CssBackgroundConstants

5.3.7    'background'

Value: <background-color> || <background-image> || <background-repeat> || <background-attachment> || <background-position>
Initial: not defined for shorthand properties
Applies to: all elements
Inherited: no
Percentage values: allowed on <background-position>

The 'background' property is a shorthand property for setting the individual background properties (i.e., 'background-color', 'background-image', 'background-repeat', 'background-attachment' and 'background-position') at the same place in the style sheet.

Possible values on the 'background' properties are the set of all possible values on the individual properties.

   BODY { background: red }
   P { background: url(chess.png) gray 50% repeat fixed }
 

The 'background' property always sets all the individual background properties. In the first rule of the above example, only a value for 'background-color' has been given and the other individual properties are set to their initial value. In the second rule, all individual properties have been specified.
