/**
 * @ngdoc directive
 * @module material.components.whiteframe
 * @name mdWhiteframe
 *
 * @description
 * The md-whiteframe directive allows you to apply an elevation shadow to an element.
 *
 * The attribute values needs to be a number between 1 and 24 or -1.
 * When set to -1 no style is applied.
 *
 * ### Notes
 * - If there is no value specified it defaults to 4dp.
 * - If the value is not valid it defaults to 4dp.

 * @usage
 * <hljs lang="html">
 * <div md-whiteframe="3">
 *   <span>Elevation of 3dp</span>
 * </div>
 * </hljs>
 *
 * <hljs lang="html">
 * <div md-whiteframe="-1">
 *   <span>No elevation shadow applied</span>
 * </div>
 * </hljs>
 *
 * <hljs lang="html">
 * <div ng-init="elevation = 5" md-whiteframe="{{elevation}}">
 *   <span>Elevation of 5dp with an interpolated value</span>
 * </div>
