Hovered element to overflow out from an overflow:hidden element css

Question

I have made a fiddle for reference: http://jsfiddle.net/kLFn9/

The overflow:hidden in question is highlighted.

Basically, i\'m using :hover:af

You can use margin-top and padding-top.

padding-top will extend your parent area, but a negative margin-top will keep it in the expected position.

It will look like you're escaping the overflow, but in fact you're not.

div {
    width:500px;
    height:200px;
    background:red;
    margin: 50px;
    overflow: hidden; /* this rule */

    background-clip: content-box; /*use this to constrain the background color within the content-box and do not paint the padding */
    padding-top: 200px; /* space required to display the tooltip */
    margin-top: -150px; /*200px - 50px of the original margin*/
}
    
span {
 background: blue;
 color: white;
 position: relative;
 top:100px;  
 display:block;   
 width: 100px;  
 margin: auto;    
}
    
span:hover:after {
    content: attr(data-name); 
    color: black;
    position: absolute;
    top: -150px;;
    left: 0;   
}

hover

This may introduce pointer events problems, but you can fix them using pointer-events then.
