Css bug and skill: IE6 empty label height problem

If the height of an empty div is set to 0 to 19px, the height of IE6 is always 19PX by default.

For example:

. C {background-color: # f00; height: 0px;/* specify any height smaller than 20px */} <Div class = "c"> </div>

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 





Tip: the code can be modified before running!
 
 
If it is not allowed, the default value is 19PX. If it is 0 PX
There are three solutions:
1.css with overflow: hidden;
2. Add comments to the div,
<Div class = "c"> <! --> </Div>
3.add line-height: 0 in CSS, and then add # nbsp in div ;,
<Div class = "c"> & nbsp; </div> (# Replace &)
Note: When the div height set for ie6 is smaller than the line-height value of ie6, ie6 sets the div height to the line-height value.
