Make Full Page White

My website is currently like this on little screens: http://d.pr/i/KwI8+ And on big screens it's like http://d.pr/i/ckmF+ But I need to have it like this: http://d.pr/i/IJc7+ Live

Solution 1:

You need to have a div that has a height: 100% and a background of #ffffff.

html, body {margin: 0; padding: 0; height: 100%;}
#page {margin: 0 auto; width: 1024px; height: 100%; background-color: #ff0000;}
