This page requires either a Gecko-based browser whose rendering code is no
older than the last day or so of July 2009 (based off trunk code at that time
in mozilla-central) or a browser with support for the unprefixed
CSS 3 background properties. Other
browsers are not supported either because I don't know they exist or because
background-size support, prefixed or otherwise, doesn't
match the latest spec, and I'd rather avoid possible confusion.
Try resizing this page, and watch what happens to the page's background
image. This page has the following CSS specified for the
element (NB: distinct
from the area containing this explanatory text):
background-image: url(cowbell.jpg); background-attachment: fixed; background-repeat: no-repeat; background-size: cover; -moz-background-size: cover;
