1. take any css footer solution demo (http://www.cssstickyfooter.com/ for example)

2. resize the browser window so that the viewport is narrower than the content

3. scroll right, see background disappearing when it's off the viewport

seems ok to me.

look at this:

Seems broken when I tried it. I never really paid very close attention to the corner of a page like this. Does it does this on all sites footers?

Why would this ever matter.

Well it doesn't look good if you are a stickler for detail. I tend to think of myself as one of those, and like I said I had never noticed it. I can't imagine it'd be a problem for most people, but there might be an instance where this screws with the design.

There are some things you are just not going to have 100% control over, doesn't matter how much of a stickler you are for details. If you're that obsessed with having a page fill the entire viewport, then you're going to have to live with the limitations that might show themselves.

Trying to achieve pixel perfection across all browsers is an exercise in futility, for the most part.
