Absolute elements ignore z-index in IE6 and IE7

In this article I will show an example of how to fix the IE 6-7 bug when absolute elements ignore z-index CSS property. In the screenshot above you can see the problem. In the sample below you can see how these styles work in your browser:

1
2

HTML:

    <div id="column1">1<div id="absoluteDiv"></div></div>
    <div id="column2">2</div>

CSS:

#column1, #column2 {
    display: block;
    position: relative;
    float: left;
    width: 100px;
    margin: 5px;
    padding: 5px;
    border: 1px solid red;
}
 
#absoluteDiv {
    display: block;
    position: absolute;
    top: 5px;
    left: 20px;
    width: 200px;
    height: 30px;
    background-color: yellow;
    border: 1px solid orange;
    z-index: 10000;
}

To fix the bug you need to add z-index property to all the parents of your absolute element until you reach the siblings that overlap your absolute element. So, here’s a workaround:

FIX:

#column1 {
    z-index: 10000;
}
