title: How can I float 1st div to left and the 2nd to the right?
body: <p>I have a DIV with two update panels inside of them. The update panels render as divs but asp.net does not let me assign a class to a div. I can do this using jQuery by assigning css to the first child, then assigning different css to the 2nd or last child. Can I do this purely with css?</p>
  
  <p>Something similar to this:</p>
  
  <pre><code>.outerdiv div
  {
     width:45%;
  }
  
  /*float:left */
  .outerdiv div(0)
  {
     float:left;
  }
  
  /*float:right */
  .outerdiv div(1)
  {
     float:right;
  }
  </code></pre>
