* @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>
* </hljs>
