/**
*
* 5.3.4 'background-repeat'
*
*
* Value: repeat | repeat-x | repeat-y | no-repeat
* Initial: repeat
* Applies to: all elements
* Inherited: no
* Percentage values: N/A
*
* If a background image is specified, the value of 'background-repeat' determines
* how/if the image is repeated.
*
* A value of 'repeat' means that the image is repeated both horizontally and
* vertically. The 'repeat-x' ('repeat-y') value makes the image repeat horizontally
* (vertically), to create a single band of images from one side to the other.
* With a value of 'no-repeat', the image is not repeated.
*
* BODY {
* background: red url(pendant.gif);
* background-repeat: repeat-y;
* }
*
*
* In the example above, the image will only be repeated vertically.
* @version $Revision: 1.4 $
