Can't get 100% height to work (read most posts here and tried for 1+ hours) - height

Question

Sorry to bother with such a beginner's question but I simply can't get this 100% height thing to work. Here is the situation (sorry, developing locally so no link):
I have a wrapping container that contains two floating elements. I followed all steps that might resolve the 100% issue, such as:
html, body {
height: 100%;
background: url(../img/bg.png);
font-family: 'SansationRegular', Helvetica;
}
.wrap {
width: 100%;
height: 100%;
height: auto !important; (apparently this fixes the issue in Chrome)
margin:40px 0px 0px 0px;
padding:0;
}
Both floating div's (sidebar and content) have height: 100% and I also added a third div container to clear the floating elements.
Still, when I add content to the content div the sidebar does not "grow" automatically. I feel I tried everything but it won't work.
Any ideas/hints are highly appreciated at this point! :)
Many thanks in advance!
P.S. I use Twitter Bootstrap as well in case that helps to solve my problem

Here's a basic example which shows how to do what you're trying to do. You should be able to take this code and adapt it to your own code.

<div class="wrap">
<div class="sidebar"></div>
<div class="content"></div>
</div>
html, body {
height:100%;
}
.wrap {
height:100%;
width:100%;
display:table;
overflow:auto;
background:#ccc;
}
.sidebar {
display:table-cell;
width:25%;
background-color:blue;
}
.content {
display:table-cell;
width:75%;
background-color:red;
}
