Child div 100% height to parent auto height

Question

Im here because other similar questions couldn't help my particular problem.

I need right div to be 100% height all the time, where the parent height depends on left div height which depends on content inside.

Here is the html:

<div class="container clearfix">
<div class="left"></div>
<div class="right"></div>
</div>

​Here is CSS:

.container{
    min-height: 10px;
    width: auto;
    height: auto;
    background-color: #eeeeee;
}

.left{
    position: relative;
    float: left;
    min-height: 100px;
    width: 50px;
    background-color: #dddddd;
}

.right{   
    min-height: 20px;
    position: relative;
    float: left;
    height: 100%;
    width: 50px;
    background-color: #dddddd;
}

.

.clearfix:after
{
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}
.clearfix {
    display: inline-block;
}

​Note:
I'm using clearfix.

Answer 1

Make the right div position:absolute; and make the parent div position:relative; and then height:100%; will work for the right div. Make sure you also adjust its x-position and width accordingly. In this example I gave it a left:50px to make sure it appears to the right of the left column.
