Cool: height: 100%; width: 100%. However, since height will relate to
the root element, which grows to fit the content, you need this:

html {position: fixed /* so our containing block is the viewport */}

body {position: absolute; /* We don't really want it fixed; that hack is
overridden by this one */
height: 100%; /* height: 100% is meaningless unless the height of the
containing block is known; by fixing the root element, it is therefore
known (the viewport) */
width: 100%}

Irrelevant. CSS is not concerned with HTML attributes.
