Question

I have some Google+ like circles, and I can’t seem to get the overflow property to work with them. I think it has something to do with the z-index property of the circles, though I’ve tried setting the z-index of the div to override that with no luck.

HTML:

<div class="container">
   <div class="circle">
      <div class="outer-circle"></div>
      <div class="middle-circle"></div>
      <div class="inner-circle">4</div>
   </div>
   <div class="circle">
      <div class="outer-circle"></div>
      <div class="middle-circle"></div>
      <div class="inner-circle">3</div>
   </div>
   <div class="circle">
      <div class="outer-circle"></div>
      <div class="middle-circle"></div>
      <div class="inner-circle">2</div>
   </div>
   <div class="circle">
      <div class="outer-circle"></div>
      <div class="middle-circle"></div>
      <div class="inner-circle">1</div>
   </div>
</div>​

CSS:

div.container {
    height: 125px;
    width: 400px;
    overflow: scroll;

What a coincidence. I was just looking for a way to expand elements outside of other elements with scrollbars and you found it by accident.

To fix this, just add position: relative; to your div.container.
