Is it possible to easily adjust the width of the columns that would apply to the whole template? I assume it's in the style.css file, but I'm not sure which attribute controls it. I'd like to make the main content area wider on all pages(single, index, and archives) and the side bar more narrow. I assume I would also need to change the width of the posts previews on the home and archive pages to fit the new layout width.
I really appreciate all the help on this forum! Thanks!
