I'm new to WordPress, new to CSS. I've been messing with my chosen themes style.css (the default theme) but I can't for the life of me discern which value changes the width of the post area. I've tried changing the widecolumn class and tried changing the page style, but neither seems to help.
The problem arises from my use of flickr. I want fairly large images, and flickr's default posting uses a 500 px image, which is a tad bigger than the left hand column in the default theme. I've changed so many things, but can't find the magic bullet. Any help is much appreciated.
