I have the Black-Letter Head theme on my page. I want to make the center column wider, move the entire menu to the right, and make my posts wider and videos bigger. I have no clue how to do this with the CSS. Someone please help me. I would greatly appreciate it.
How much wider do you want the content area? Right now it is at 450px.
Keep in mind that there are still a lot of people out there on 1024px wide monitor resolutions so the total outside width of the main page area should be kept at 990px maximum. Right not the theme is at 760px which would mean you can increase the main content column by up to 230px.
