This is a brilliant tutorial if you want to learn WP Themes http://www.wpdesigner.com/2007/02/19/so-you-want-to-create-wordpress-themes-huh/ Its helped me a lot.
Basically edit your style.css file and find the width of the sidebar. Work around that. I mean increase the "width" of your sidebar inside layout. it should look like this #right_siderbar { width: 200px; } change the width to something wider .
The overall width of the theme is dictated by the background image for the header at 950px: http://www.repcodes.com/wp-content/themes/coolmist/images/header.gif So you will need to either widen the entire theme and then edit the header image to fit or take some some space from the content area and add it to the sidebar. Doing the latter may effect the large images you have on some of the posts and cause them not to fit. I take no responsibility for what happens to your blog if this completely screws up your theme. What I am about to type looks like it may work but without experimenting with the theme I am not sure and don't know what other items can be effected by this edit. So be sure to backup your files prior to editing or upload the theme on a test blog. To rob from the content and add to the sidebar start by backing up all the theme files. Then edit style.css to reduce the content area, on your theme it looks like this is the area: .post-wrapper { padding-left: 10px; width: 676px; margin-left: -20px; Code (markup): try reducing the width by the amount you want to add to the sidebar shown below. #sidebar { float: right; padding: 0px 15px 10px 10px; width: 210px; margin-right: 15px; margin-top: 0px; Code (markup): This may effect other items that will need tweaked as well and if it totally screws up your theme just paste the unedited code from the backup back into the theme. You can also try to reduce the padding on both to gain a bit of space.
