I'm fairly new to druapl. I'm using Druapl CMS, I've got a few questions.

1) How do I remove the black bar at the bottom, I've already remove all the footer blocks, but there is still a huge black bar at the bottom of the site.

2) On wide screens, the white background stops and there's a drupal logo wall visible 'behind' the white background on the right. How do I make the white background go all the way?

3) How do I change the background and font colors?
