H2, so it is silver. In the second, the elementadjacent to the H2 is a UL,which does not match the rule, and neither does the paragraph rightafter that. Finally, even though there is text directly after thethird H2, it isn't part of an element, sothe paragraph right after the text matches the rule and is coloredsilver. All this is demonstrated in Figure 10-5.

Figure 10-5. Selecting adjacent elements

If you wanted to make any element immediately following an it would have been if the element had not been positioned. Forexample, consider a nonpositioned element whose top edge is 3 emsfrom the top of its containing block. If the element is thenpositioned and given a top ofstatic-position, then the top of the positionedelement will be 3 ems from the top of the containing block. Later inthe chapter, we'll see how this can be useful.

The other value, auto, allows for some even moreinteresting effects. It acts much the same as setting

DIV {width: 400px; border: 1px solid black;}P.wide {margin-left: -50px; width: auto; margin-right: 10px;border: 3px solid gray;}

In this case, not only does the paragraph spill beyond the borders ofthe DIV, but also beyond the edge of the browserwindow itself!

As Figure 7-58 demonstrates, the background of an element extends into the padding. As we discussed before, it also extends to the outer edge of the border, but the background has to go through the padding before it even gets to the border.

The default value of padding is 0 (zero), and padding values cannot be negative.
