I like the new default theme, but it would be nice if the dimensions were more customizable. I just want to do three things:
1) The sidebar seems to be 220 pixels wide. How can i increase it to 260 pixels and reduce the main content area by the same amount?
2) The site title above the header image seems unnecessary. Is it possible to remove that title as well the tagline?
3) The header image is cool, but it's too thick. Is it possible to reduce the height of the image?
If someone could help me with even one of these things, i'd be very grateful. I'm guessing i have to edit the CSS file but i don't have much experience with CSS. I just don't want to leave any loose ends that could cause formatting problems in the future.
