Specifying Window Sizes in HTML

Hey guys-

I’m creating a new Landing Page in HTML. It is using a “WP-Sales Page” Plugin.

I created and imported the images in Photoshop and inserted them into the page.

However, I want ALL of the Page to have a White Background, not just the images. Thanks for your help.
