I want to add an additional sidebar to my zen based theme with fixed columns.
I added it to the theme info, and printed it in the page.tpl.php file, but I don't know how to configure its CSS files to make it look correct; I don't know how to make the content region expand to fill the available space when there is an empty region with no blocks in it like with Zen.
My theme contains 4 columns:
- left sidebar 1 (130 pixels)
- left sidebar 2 (255 pixels)
- content (509 pixels)
- right sidebar (130 pixels)
The total width would be 1024 pixels.
How can I do that?
