Glad I found this forum.
I have a very annoying problem. For one of my websites the <body> tag doesn't cover the whole page. So when I try to add a background image, the image only cover half of the page. I used the W3C validators, firebug, other validators etc. I really can't figure this out. I also tried to set height and width to the <html> en <body> tag but that didn't fixed my problem neither. I do have some html and css skills but this one I really can't figure out. Probably I don't see it anymore or I'm misreading something.
My website is currently in development and can be found here: http://meules1.webshopapp.com/
