Extending Sidebar with CSS

Posted on 2007-11-25
Last Modified: 2010-08-05
I have a page with a wrapper div.  In the wrapper I have a sidebar div for the left side navigation and a main div for the content.  I am can not figure out how to make the side bar  stay even in length with the main page.  Right now the sidebar is floating next to the  main div.

Things I have tried;
placed the main div inside the sidebar div
set sidebar height to 100% - thought I could extend it to height of the wrapper div.

Any suggestions or code improvements would be appreciated.

#main {



		margin:0 auto;


		border: Solid 1px red;




	#main H1


    display: block;

	font-family: verdana;

	font-size: 20px;

	color: #fff;


	#sidebar {

	height: 514px;


	background: black;

	background-image: url(images/leftnavguitar.JPG);

	background-repeat: no-repeat;

	background-position: 0% 100%;

	margin: 0px;

	Padding: 0px;

	border: Solid 1px yellow;


#sidebar ul


list-style-type: none;

padding: 0px;

margin: 0px;

border: Solid 1px green;


#sidebar li


background-image: url(images/nav_arrow.gif);

background-repeat: no-repeat;

background-position: 1% 50%;

margin: 3px 0px 3px 0px;

padding: 0px 0px 0px 14px;

font-family: verdana;

font-size: .75em;

border: Solid 1px yellow;


#sidebar li A:link{text-decoration: none; color:#fff;}

#sidebar li A:hover {text-decoration: underline; color: #E7B33B;}

I would recommend setting the height attribute of the parent element, wrapper div in this case, to 100%. Here is a simple example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">




<style type="text/css">

#divWrapper, #divSideBar, #divMain {


    border:1px solid red;


#divSideBar {







<div id="divWrapper">

<div id="divSideBar">

	 Side Bar


<div id="divMain">
