Try using Firefox with the Firebug add-on for this kind of CSS troubleshooting. Or use whatever developer tool is available in your web browser.
OK, but aren’t there any code in Style.css that I can copy and change the width for the sidebar? I found the code part for the main page and it worked.
The element you are looking for is the #secondary id – there are a number of place in @media where you’ll need to change the width.
You’ll also need to adjust the width of the other containers in order to accommodate the new sidebar width.
Hope that helps point you in the right direction.

OK, thanks.. I’ve found it and I just changed the background color so it became white like rest of the page so it doesn’t appear so heavly.
