Div height:0px does not work?

Question

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

The div expands to show it

Answer 1

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

Answer 2

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

Answer 3

For me, on Windows 10, Firefox 58.0.1, it wouldn't hide completely unless using this:

display: block !important;
line-height: 0 !important;
height: 0 !important;
overflow: hidden !important;
zoom: 1 !important;
padding: 0 !important;
margin-bottom: 0;
border: none;

#yiv1734505183 .yiv1734505183portrait{
    display:none;
    font-size:0;
    max-height:0;
    line-height:0;
    padding:0;
    overflow:hidden;
}

@media (min-width:481px){
    #yiv1734505183 .yiv1734505183mobile-hide{
        display:block;
        overflow:visible;
        width:auto !important;
        max-height:inherit !important;
        min-height:auto !important;
    }
}
@media (min-width:481px){
    #yiv1734505183 .yiv1734505183portrait{
        display:none;
        font-size:0;
        line-height:0;
        min-height:0;
        overflow

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

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;
