Figure 8-27. Scaling images with the width property

It's also possible to scale an image (or other replacedelement) using height:

<IMG SRC="test.gif" STYLE="display: block;" ALT="test image"><IMG SRC="test.gif" STYLE="display: block; height: 50px;" ALT="test image"><IMG SRC="test.gif" STYLE="display: block; height: 200px;" ALT="test image">

{background: green;} andwe're set. Or are we?

Not quite, no. In the old page, the navigation bar was separated slightly fromthe main display, but ran right up against the sidebar, therebycreating a sort of inverted green "L" shape. We want tomake sure that this is still the case in the new setup. This is mosteasily accomplished by making sure that the division has no paddingor border set, and that it is guaranteed to be as wide as the tablecell in which it's found. Plus, we want the bar to have aelement is not necessarily its parent element. In fact, it often isnot, unless the author takes steps to correct this situation.Fortunately, that's easy to do. Just pick the element that youwant to use as the containing block for the absolutely positionedelement, and give it a position ofrelative with no offsets. Thus:

P.contain {position: relative;}

Consider the example in Figure 9-19. It shows twoparagraphs that contain identical text. However, the first paragraph

If only one keyword appears, then the other is assumed to becenter. Table 6-1 showsequivalent keyword statements.

Table 6-1. Position Keyword Equivalents

So if you want an image to appear in the very top center of eachparagraph, as in Figure 6-38, you need only declare:

it's outside the parent DIV !

Figure 8-22. The effects of a negative top margin

With a negative bottom margin, though, it looks as though everything following the paragraph has been pulled upward. Compare the following markup to the situation shown in Figure 8-23:

What's really happening in Figure 8-23 is that the elements following the DIV are placed

Figure 7-16. Collapsed versus uncollapsed margins

Correctly implemented user agents will collapse the vertically adjacent margins, as shown in the first list in Figure 7-16, where there are 15-pixel spaces between each list item. The second list shows what would happen if the user agent didn't collapse margins, resulting in 25-pixel spaces between list items.

Another word to use, if you don't like "collapse," is
