I want to make to 2 `div`'s height equal, if one is bigger another should stretch to its height. I want to use only `CSS`. Following is my code([Fiddle](http://jsfiddle.net/iiison/Q8m4u/)):

HTML:

```
<div class="common">
    lorem ipusm random text just for check
</div>
<div class="common">
    lorem ipusm random text just for check lorem ipusm random text just for check
</div>

```

CSS:

```
.common{
  border:1px solid red;
  float:left;
  margin-left:5px;
  width:20%;
  padding:5px;
}

```

This is [fiddle](http://jsfiddle.net/iiison/Q8m4u/) for this
