 /**
- *   <H4>
- *     <A NAME="text-align">5.4.6 &nbsp;&nbsp; 'text-align'</A>
- *   </H4>
- *   <P>
- *   <EM>Value:</EM> left | right | center | justify<BR>
- *   <EM>Initial:</EM> UA specific<BR>
- *   <EM>Applies to:</EM> block-level elements<BR>
- *   <EM>Inherited:</EM> yes<BR>
- *   <EM>Percentage values:</EM> N/A<BR>
- *   <P>
- *   This property describes how text is aligned within the element. The actual
- *   justification algorithm used is UA and human language dependent.
- *   <P>
- *   Example:
- *   <PRE>
- *   DIV.center { text-align: center }
- * </PRE>
- *   <P>
- *   Since 'text-align' inherits, all block-level elements inside the 'DIV' element
- *   with 'CLASS=center' will be centered. Note that alignments are relative to
- *   the width of the element, not the canvas. If 'justify' is not supported,
- *   the UA will supply a replacement. Typically, this will be 'left' for western
- *   languages.
- * @version $Revision$
+ * @spec http://www.w3.org/TR/2008/REC-CSS1-20080411/#text-align
