/**
 *   
 *        'text-indent'
 *   
 *   
 *   Value: <length> | <percentage>

 *   Initial: 0

 *   Applies to: block-level elements

 *   Inherited: yes

 *   Percentage values: refer to parent element's width

 *   

 *   The property specifies the indentation that appears before the first formatted
 *   line. The value of 'text-indent' may be negative, but there may be
 *   implementation-specific limits. An indentation is not inserted in the middle
 *   of an element that was broken by another (such as 'BR' in HTML).
 *   

 *   Example:
 *   
 *   P { text-indent: 3em }
 * 
 * @version $Revision: 1.4 $
