title: find elements with position:attribute
body: <p>I would try to find all "absolute" elements in my page; with jQuery I though it would be something like</p>
  
  <pre><code>$('[position="absolute"]')
  </code></pre>
  
  <p>but on ff 10.0.2 I cannot find an element...</p>
  
  <p>Also, I cannot run the exaple code on <a href="http://api.jquery.com/attribute-equals-selector/">http://api.jquery.com/attribute-equals-selector/</a> 
  Is there something wrong on this syntax?</p>
