Let 2 floating divs take remaining space to the bottom of the page


I have 2 floating divs:

1 has a width of 25% and floats to the left
1 has a width of 75% and floats to the right

I want these divs to fill up the remaining space to the bottom of the page to where my footer sticks. How do I make this happen?

HTML code =>
<div class="content">
<div class="leftcolumn left">
<div class="submenu">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>

<div class="rightcolumn right">
 <div class="page_content">

Open in new window

CSS code =>
width: 25%;
width: 75%;

Open in new window

I attached a file which shows the two div's with nice little purple arrows :)

Thanks in advance!

you should be able to implement this to your needs...

soi if I understood correctly you want the height to be equal in both of the foot containers right? in order to form what appears to be only one footer and not 2 parts of a footer
