Map width on a single page and removal of top image

Hi

1. I’m using Supreme and I like the front page but I don’t like the image to be on the top part of About, Map and Contact us. I tried using the Siteorigin CSS plug in and was able to enter in the css to remove the picture at the top of the pages but then the home page disappeared as well. Is there anyway to keep the home page as is and remove the pictures from the top of the other pages?

2. I’m trying to get the Map page to have a full length map at the top. I set the page to full length but it isn’t showing up as full width.

Thanks in advance
