Along the way, we'll build a CSS library of components that you can use as a starting point for your pages. You'll be able to open the sample files, copy the markup into your XHTML, copy the styles into your style sheet, and then just fine-tune them for your particular needs. As you work with CSS, you will find yourself creating a library of your favorite component styles that you can copy into your project style sheets, thereby saving yourself hours of time rebuilding components you have already made.
