10.9. Summary

CSS2 obviously covers a lot of ground, and exploring it in detail would probably have added at least four more chapters to this book, not to mention dramatically bulking up some of the chapters that already exist. However, since so little of CSS2 has actually been implemented at this writing, we felt it was better to provide an overview that was light on details. After all, the specification may change as implementations reveal flaws, and we'd rather stick to describing things that are fairly reliable.

For quick reference purposes, Table 10-1 gives a quick summary of everything new in CSS2.

WARNING

InternetExplorer 4.x and 5.x bothrecognize :hover on anchors only. As of thiswriting, no other browser will recognize :hover

For the most part, the text in both paragraphs looks fairly normal.In the second one, however, the place where the boldface elementwould have appeared is simply closed up, and the positioned textoverlaps the some of the content. There is no way to avoid this,short of positioning the boldfaced text outside of the paragraph (byproperties in Chapter 10, "CSS2: A Look Ahead".

8.2.4. Block-Level Replaced Elements

Block-level replaced elements are also subject to a few differences in how formatting is handled. The most important is that replaced elements are assumed to have an intrinsic height and width; for example, an image will be a certain number of pixels high and wide. Given this,
