The use of cascading style sheets (CSS) gives an homogeneous presentation of web site pages, with a virtually unlimited control on layout.

The counterpart is the necessity to know a minimum of CSS syntax (see the quick reference on CSS annex). You may learn with samples, by using predefined style templates, and gradually modifying them. By using preview mechanisms and automatically generating web sites, you get immediate effects of the changes to the style template.

For example, by changing title class style, you control how all document titles that will be displayed, and immediately check the effects thanks to the preview feature.
