Q:

jquery resizable not working properly

I am quite new in javascript/jquery.  I am making resizable divs using jquery-ui-resizable.  Here I have created the fiddle but can't figure out why jquery ui resizable is not working. 
    <div class="container">
  <div class="left-container">
  </div>
  <div class="right-container">
    <div class="child first">
    </div>
    <div class="child second">
    </div>
   </div>
</div>

$(".child").resizable({
   //"handles": "w, e"
})

Any help would be appreciated.

A:

You must add a jquery-ui theme in order for this to work. 
Try this line of code:
<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/smoothness/jquery-ui.css">
