So you think you know CSS? Take your CSS skills to the next level and
learn to write organized and optimized CSS that will improve the
maintainability, performance, and appearance of your work.
You'll learn how document flow and CSS positioning schemes will help you
make your documents more accessible. You'll discover the great styling
possibilities of CSS paired with semantic structures like Microformats
and RDFa, while enriching the self-describing semantics of XHTML
content. Learn how to group logically related declarations, minify style
sheets, and prevent performance bottle necks such as reflows and
repaints. With support for CSS enjoying unprecedented ubiquity, you can
finally use such features as generated content, complex selector chains,
and CSS3's visual properties, like box-shadow, in your projects.
