The animated GIF logo was created by sequencing still GIF's earlier in the chapter? Here's one example of how it works and how it can be very useful.

Another important point is that when an element is positioned, it establishes a containing block for its descendant elements. For example, we could absolutely position an element and then absolutely position one of its children, as shown in Figure 9-23.

Figure 9-23. Nested absolutely positioned elements

The small box B in the lower-left corner of the element A is a childAnother way to look at it is that positive values cause inwardoffsets, moving the edges toward the center of the containing block,and negative values cause outward offsets.

TIP

The description of offsetting the outer edges is based on an erratum.The original CSS2 specification actuallysays that the content edges are offset, but it has been widely agreedthat this is a serious error, and in fact, readings of other parts ofthe specification show that it is the outer edges that are offset. element is not necessarily its parent element. In fact, it often is not, unless the author takes steps to correct this situation. Fortunately, that's easy to do. Just pick the element that you want to use as the containing block for the absolutely positioned element, and give it a position of relative with no offsets. Thus:

P.contain {position: relative;}

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

/* This is a comment, in which we findanother comment, which is WRONG/* Another comment */and back to the first comment */

However, it's hardly ever desirable to nest comments, so thislimitation is no big deal.

If you wish to place comments on the same line as markup, then youneed to be careful about how you place them. For example, this is the
