title: Animating marginLeft with jQuery
body: <p>I can't figure out to animate marginLeft with jQuery. I need it to subtract 938px every time a user clicks on a link, which was working fine when I was using <code>.css()</code>, but I can't figure out how to make it work with <code>.animate()</code>.</p>
  
  <pre><code>$("#full-wrapper #full").animate({
      marginLeft, -=938px
  }, 500);
  </code></pre>
  
  <p>Can anyone figure out why this doesn't work? This was my CSS version:</p>
  
  <pre><code>$("#full-wrapper #full").css("marginLeft","-=938px");
  </code></pre>
  
  <p>I was using CSS3 for animation, but need to make it work in older browsers.</p>
