I want a page that has two fixed-width columns on the left and a main column that fills up the rest of the width of <body>. Within each column, I want to place some <div> object on the top and a <ul> object that fills up the rest of the height. I tried the following, but could not make the height of the <ul> objects automatically adjust to fill in the height. Rather, it overflows to the bottom as much as the height of the <div> above them.
<html>
<style>
body{
margin:0;padding:0;
overflow: hidden;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
background-color:red;
}
.column{
float: left;
background-color:blue;
}
.column>ul{
height: 100%;
width: 100;
overflow-y: scroll;
overflow-x: hidden;
background-color:green;
}
#main-column>ul{
height: 100%;
overflow-y: scroll;
overflow-x: hidden;
background-color:brown;
}
</style>
<body>
<div class="column">
<div>Column 1 Title</div>
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
</div>
<div class="column">
<div>Column 2 Title</div>
<ul>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
<div id="main-column">
<div>Main Column Title</div>
<ul>
<li>Item 5</li>
<li>Item 6</li>
</ul>
</div>
</body></html>
How can I make it so that height of the <ul> objects are automatically adjusted to fill up the remaining height?
This is what I get so far. The scroll bar is cut off and extends below the window border, which indicates that its height is overflowing.

If you give the column titles a fixed height, you can use that along with
position: absoluteon theuls to get the layout you want. Demo: http://jsbin.com/ecilob/1/editHTML:
