OT: Is this possible with CSS

Hi, I am having a nightmare trying to replicate a 3 column site with CSS - it nearly make me want to use <table>'s (did i say that out loud) To see what i am trying to create go to http://andyjarrett.co.uk/css.gif For those of you who you can i am trying to create a 3 column site with a header and footer.             h e a d e r ----------------------------------------- left col  | content  |  right col -----------------------------------------              f o o t e r The 3 middle columns should always be 100% of the gap between the header and footer. With the left and right columns being fixed. In tables it would be <table border="0" width="100%" height="100%">   <tr>     <th colspan="3"> </th>   </tr>   <tr>     <td width="100"> </td>     <td> </td>     <td width="100"> </td>   </tr>   <tr>     <td colspan="3"> </td>   </tr> </table> I have seen some templates but they rely on the content column to be the longest. I have never found a solution as solid as the tables version. Its gotta be do-able - actually its probably well easy but I'm just not seeing it. Cheers for any help Andy J www.andyjarrett.co.uk
