New Easy-Clearing
.group:after {
  content: ".";
  display: block;
  height: 0;
  clear: both;
  visibility: hidden;
}

Using conditional comments, let's add the proper code to handle IE 6 and IE 7 (IE8 supports the :after pseudo-elements; no extra code is necessary).

New Easy-Clearing for IE
/* IE6 */
* html .group { height: 1%; }

/*IE7 */
.group { min-height: 1px; }

I've been using the group class on my latest projects and I'd like to share a small tip, when clearing list items, with you.

Normally, we'd have the group class on every LI, like so:

Clearing List Items the Old Way
<ul class="comments">
  <li class="group">
    <img src="carla.jpg" alt="Carla&#x27;s Picture" />
    <p>Tiny and I miss you</p>
  </li>
  <li class="group">
    <img src="steven.jpg" alt="Steven&#x27;s Picture" />
    <p>I need a favor! It will take you 5 seconds.</p>
  </li>
  <li class="group">
    <img src="buzz.jpg" alt="Buzz&#x27;s Picture" />
    <p>I speak gibberish</p>
  </li>
</ul>

Although the markup doesn't look very bad, we can make things better by introducing a new class (groupList) and adding it to the UL.

Clearing List Items the New Way
<ul class="comments groupList">
  <li>
    <img src="carla.jpg" alt="Carla&#x27;s Picture" />
    <p>Tiny and I miss you</p>
  </li>
  <li>
    <img src="steven.jpg" alt="Steven&#x27;s Picture" />
    <p>I need a favor! It will take you 5 seconds.</p>
  </li>
  <li>
    <img src="buzz.jpg" alt="Buzz&#x27;s Picture" />
    <p>I speak gibberish</p>
  </li>
</ul>

Phew, the markup looks much cleaner! Now that we've fixed it, let's add the .groupList > li selector to the existing .group styles.

Extending .group
.groupList > li,
.group:after {
  content: ".";
  display: block;
  height: 0;
  clear: both;
  visibility: hidden;
}

Wait! How about the beloved IE?

Extending .group IE
/* IE6 */
* html .groupList li,
* html .group { height: 1%; }
* html .groupList li li { height: auto; } /* Resets nested LIs */

/*IE7 */
.group > li,
.group { min-height: 1px; }
