I am working on a site using the tb-sirate 7.1.0 theme and I have added couple of regions and reposition the logo and slogan due to the additional header-right region that I created. However, things seems to be showing fine on Mozilla and Chrome, but not in IE. Also, I need help in adding these additional region to the mobile settings so if someone was to access the site via mobile, they will see everything stand out perfect. Another help will be to allow content that I show through panel column take up the entire area of panel column... As I have removed the images that use to show up on the panel column, I will like to use the entire space.

Thanks for your help
