title: How to set div's height in css and html
body: <p>I'm using Twitter Bootstrap. I wrote in my html:</p>
  
  <pre><code>&lt;div style="height:100px;" class="span12"&gt;
  asdfashdjkfhaskjdf
  &lt;/div&gt;
  </code></pre>
  
  <p>Why the height is not 100px when I open that page?</p>

    <p>For posterity, the original code was : <code>&lt;div height="100px"&gt;</code></p>
