Why Does `overflow: hidden` Not Work on a `position: relative` `ul` in IE6 and IE7?

IE6 IE7 CSS Problem: Overflow: Hidden Not Working with Position: Relative

The issue arises when using overflow: hidden; to hide inactive slides within a slider in IE6 and IE7. The overflow property fails to work when applied to an ul element that has position: relative; set on it. This hindrance prevents the element from being correctly concealed.

Investigating the provided HTML code reveals that position: relative; is indeed applied to the ul element. However, this is necessary for the slider's JavaScript functionality, which relies on adjusting the left attribute of the ul to slide the content.

Solution:

The solution to this problem lies in understanding a known bug in IE6 and IE7. To overcome this bug, add position: relative; to the container of the ul element. In the provided code, the body is the container. Therefore, the recommended fix is to add a div directly under the body and apply position: relative; to it.

To illustrate the fix:

<code class="html"><body>
  <div style="position: relative;">
    <!-- Slider code here -->
  </div></code>

By adding this extra div with position: relative; to the code, the overflow: hidden; property on the ul element will start functioning correctly in IE6 and IE7, allowing the inactive slides to be hidden as expected.
