The CSS adapters don't replace existing controls; they complement them by altering the HTML after the controls have rendered to the browser. They still come as a web download (that's why I am referring to them from the book) and can be installed as an "afterthought" to fix an existing site.
Although you can use them in PlanetWrox without much problems, my recommendation is to skip them for a while. They can easily be installed afterwards, so it's probably easiest to stick to the book as much as possible.
Cheers,
