title: Prototype.js: reset setStyle
body: <p>Is there's any way how to reset styles back to what's in my CSS?</p>
  
  <p>Example:</p>
  
  <pre><code>#foo {width: 50px; height: 50px; position: absolute; top: 150px; left: 250px;}
  
  
  function moveFoo(newpostop, newposleft){
    $('foo').setStyle({top: newpostop+'px', left: newposleft+'px'});
  }
  </code></pre>
  
  <p>Now when I'm done with it, I'd like to move foo back when it was. I know it can be hard-coded, but I need to do this with 25 different divs.</p>
  
  <p>Thanks</p>
