When there is a float in the child element of li, a 4px gap bug will occur under the

element in IE6/IE7.

The code is as follows:

<ul class="list">
<li><div>vapour</div></li>
<li><div>百度</div></li>
<li><div>淘宝</div></li>
<li><div>迅雷</div></li>
</ul>

After testing, it was found that the floating sub-element of li is a necessary condition for the occurrence of this bug. The necessary and sufficient condition for the occurrence of this bug is that the sub-element of li is floating and li has one of the following CSS attributes set: width, height, zoom, padding -top, padding-bottom, margin-top, margin-bottom.

Now that we know the conditions for this bug, we have a solution:
Method 1:
#list div sets clear:left|both, then #list li cannot set width, height, zoom.

Method 2:
#list li sets float:left. At this time, #list li can set width, height, and zoom.
#list li sets clear:left|both. At this time, #list li cannot set width, height, and zoom.

Method 3:
This bug in IE6/IE7 can be solved by setting vertical-align:top|middle|bottom to the div in li. It's too weird, just add that the value of vertical-align is one of the three.

The code is as follows:
