For example, we could center it, with the result depicted in Figure 6-36:

BODY {background-image: url(bigyinyang.gif);background-repeat: no-repeat;background-position: center;}

an element from exceeding a certain size, as in this:

max-height: 30em; max-width: 20em;

The question here, though, is what happens if the content of the element doesn't all fit into the specified element size. Does it get cut off at the boundaries, or does it spill outside the positioned element? That's what the next section will explore.

isn't on the list of named colors. This is due to the fact that most web browsers recognize as many as 140 color names, including the standard sixteen. There are two problems associated with using these extra names, though. The first is that not all browsers will recognize them; Opera, for example, sticks with the standard 16 colors, at least in the Opera 3.x series. Far from being a failure on their part, this represents a remarkable commitment to standards support, even though it might confuse or annoy many web designers.

The second problem is a little more fundamental: there are no

This gives us our dark green and dark gray hyperlinks.

Now for headings. They're all supposed to be in a sans seriffont, but H1s have some special rules. In order tocover all the bases in a compact manner, we declare:

H1, H2, H3, H4, H5, H6 {font-family: Verdana,sans-serif;}H1 {color: rgb(0%,40%,0%); border-bottom: thin solid; width: 100%;}

With the second declaration, not only do we use the standard color,but we enhance the idea of "underlining" by setting abottom border that will extend from the left edge of the text all thesafe bet that most people don't. It would make far more senseto specify a single font family for the whole document and thenassign weights to various elements. You can do this, in theory, usingthe various values for the property font-weight. Afairly obvious font-weight declaration is this:

B {font-weight: bold;}

This says, simply, that the B element should bedisplayed using a boldface font; or, to put it another way, a fontthat is heavier than is normal for the document, as shown in Figure 5-8. This is what we're used to, of course,
