The background will stretch with the screen size to completely fill it out.
The first thing I did was make a .jpg image the same size as my page to use for the standard background in my center area on my VSD page. This image is 1000x1000. Brown on the left half and white on the right half. Next I added a html box to my page and pasted the code below into it. Next I used the "Add files" tool and added a directory called "backstretch" I then added my splitcolor.jpg image. Yours will be different and you can adjust the image name in the code to match for SEO reasons. Also add the two .js files inside the folder in this link. backstretch.zip
Add this code to the Body HTML of a HTML box.
