Overlapping Divs

I require 2 overlapping divs, which look like the one below. ------------------------------------ | | | | ------------------ |

Solution 1:

I think you want something like this:

html

<divclass="parent"><divclass="a"></div><divclass="b"></div></div>

css

.parent {
  position: relative;
}

.a {
  position: absolute;
  width: 100px;
  height: 100px;
  z-index: 100;
  background: red;
}

.b {
  position: absolute;
  width: 80px;
  height: 180px;
  z-index: 110;
  left: 10px;
  background: blue;
  top: 10px;
}

Edit: in your case parent = contentContainer, a/b = leftContainer/rightContainer

Solution 2:

I have changed like this:

#rightContainer {
    /*float:right ;*/width:20%;
    /*margin:0px;*/margin-top: 30px;
    margin-left: 30px;
    padding:0px;
    position:relative;
    background-color:Lime;
}

You may change the "30px" as you like. I have tested in FireFox only.

Solution 3:

You will have to use top, left and z-index properties for that.

Solution 4:

Im not really sure how to use the z-index

But i think this might help in the style tag

margin:-50px -50px0px0px;

the minus property works, how well it does should be all about testing
