I am trying to create a site that looks like Google. I want to put the black navigation bar at the top of the page and remove the Header and Search box. I also would like the link that you have clicked on to change colour like when it’s scrolled over.
Do not edit the Twenty Eleven theme. It is the default WordPress theme and having access to an unedited version of the theme is vital when dealing with a range of site issues. Create a child theme for your changes. Once your child theme is active, we should be able to help with the customisation.
