code is as follows:  


li {width: 300 px; Height: 23 px; Line - height: 25 px:}
<Ul>
<Li> Space is very big </li>
<Li> Space is very big </li>
<Li> Space is very big </li>
<Ul>

after the above definition of li line spacing should be 23 px, but IE was 28 px, for more than 5 pixels, the reason why I don't know, the solution is as follows (red test OK) :
1. Solving li produce blank space under the IE5 method: if li defines the width, you need to define vertical again in li - align: bottom; .
2. The width is best not to define in UL, defined in LI or UL outer DIV.
3. The best way to write LI, LI, to write inside the height and width, and the vertical - align: bottom; (for ie5/win a bug), or add a layer on the outside of the ul div, and defines the width, so in li don't have to define the width and vertical - align: bottom; , also showed normal (IE5 won't produce blank space below), but still want to define the height.

This concludes the body part
