/**
 * The LineHeightSC represents CSS "line-height" values. The allowed
 * values are:
 * <ul style="font-family: monospace;">
 *         <li> normal </li>
 *         <li> [multiplier] -  a non-negative number</li>
 *         <li> [specific line height] - a length value (%, px, in, etc.) </li>
 * </ul>
 * <br /><br />
 * The <code>StyleComponent</code> (SC) is the most basic of the three building pieces
 * of CSS styles. It combines a CSS property value with a ValidatorRule to ensure that
 * the value follows a certain format.<br /><br />
