Div height:0px does not work?

Question

<div style="height:0px;max-height:0px"> </div> 

Setting a div height to 0px does not seem to work.

The div expands to show its contents, how do we prevent this from happening?

Answer 1

If you really want to be sure it's gonna be have no height you could use something like this:

display: block; line-height:0; height: 0; overflow: hidden; 

If you're still having problems on IE, you could also add

zoom: 1; 

to it in a stylesheet targeted at IE with a conditional comment. That'll trigger the hasLayout property in IE.

And display:none isn't the same as setting it to zero height. Just look at the various clearfix solutions for a case where not removing it from the flow is crucial.

Answer 2

Set overflow:hidden. Otherwise the content will expand the wrapping element.
