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.

Controlling line breaks, alignment and indents

The &nbsp; character is a non-breaking space that can be used to insure line breaks don't occur between certain pairs of words inthe basics and then work our way up.

The default value of none means about what you'd expect: no image is placed in the background. If you want a background image, then you need only give this property a URL value:

BODY {background-image: url(bg23.gif);}

Due to the default values of other background properties, this will cause the image
