title: how to make an image inside div fill the entire div?
body: <p>Currently I'm using this code:</p>
  
  <pre><code>&lt;style type="text/css"&gt;
     .icondiv{
        border:1px solid;
        content: url(image.png) 100% 100%;
     }
  &lt;/style&gt;
  
  &lt;div class="icondiv"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>The output is like, the image stays in 1/4 of the div. How can I make the image fill the whole?  I already checked the image and it has no extra whitespace. </p>
