title: How do I make a div expand to the width of the page with css?
body: <p>I have a page with a couple of divs, sort of like this:</p>
  
  <pre><code>&lt;div id="div_one"&gt;blah blah blah&lt;/div&gt;
  &lt;div id="div_two"&gt;blah blah blah&lt;/div&gt;
  </code></pre>
  
  <p>I want them to be centered horizontally, one after the other and for the second to expand to the width of the page. </p>
