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

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

Answer 2

Try overflow:hidden

Answer 3

You could try adding "overflow:hidden" to the style

Answer 4

Try to also set line-height: 0;

And if you want to hide your div completely, use display: none;

Answer 5

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 6

You haven't said which browser you're using, but I'm assuming IE, as it's the only browser I know of which mistakes height for min-height . Like everyone else has already said, overflow:hidden; will work, or line-height: 0;, but you only need one of them.

Setting height: 0; will have allready triggered IEs hasLayout, so no need for zoom:1; in this case.

Answer 7

Not quite sure what you're trying to do, out of context, but try this:

display:none;
overflow:hidden:
height:0;
line-height:0;
border:0;
margin:0;
