title: How to change div width with jQuery from 50 to 100% and back
body: <p>I am working on test website (i am learning html+css) and now I need your help with something. </p>
  
  <p>I have 3 divs with texts(width 50% each) and in upper left corner of every div i want to have image with "+" symbol. When user click on in, symbol + will change itself to - and width of div (just for that one div).</p>
  
  <p>Good example is here on pic: <a href="http://i39.tinypic.com/9va7pz.png" rel="nofollow">http://i39.tinypic.com/9va7pz.png</a> (but i want "-" symbol too)</p>
  
  <p>Can someone shows me how to do that? I have no chance with JS (newbie).</p>
  
  <p>Of course if it is possible to animate it (not only change width)</p>
  
  <p>(sry for bad english - hope you will understand what i want)</p>
