Sidebar full height

Hi

I am creating a theme for my new site.

My problem is that no matter what I do I cannot get the sidebar to show to full length, only the size of the current content.

The site is at http://www.vomedia.co.uk

As you will see, the sidebar does not run to the same length as the ‘content’ div.

The sidebar is floated left while the content is floated right. Both having an image as background repeated y

I have tried putting both sidebar and content divs within another div and give a full image to cover both sidebar and content but it doesn’t show up.

I know I have managed this in tables in other designs but wanted to stick to the div layout.

Can any one assist in my dilemma? Thanks in advance for any help offered.
