title: Set size on background image with CSS?
body: <p>Is it possible to set the size of the background image with CSS?</p>
  
  <p>I want to do something like:</p>
  
  <pre><code>background: url('bg.gif') top repeat-y;
  background-size: 490px;
  </code></pre>
  
  <p>But it seems it's totally wrong to do it like that...</p>
