title: Resize images from sprite
body: <p>Is it possible to resize images which we receive from sprite.
  I mean like this:</p>
  
  <pre><code>background: url(../images/sprite.png) no-repeat -1px -1170px;
  display: block;
  height: 14px;
  width: 14px;
  </code></pre>
  
  <p>Is it possible to change width and height from sprite? For example if I have pencil icon in sprite with resolution 40x40 but I want to display this pencil icon like 20x20 pixels</p>
  
  <p>Thank you, in advance.</p>
