The CSS layout cookbook aims to bring together recipes for common layout patterns, things you might need to implement in your sites.

CSS is among the core languages of the open web and is standardized across Web browsers according to W3C specifications. Previously, the development of various parts of CSS specification was done synchronously, which allowed the versioning of the latest recommendations.

Declarations not set in the highest priority source are passed on to a source of lower priority, such as the user agent style. Different styles can be applied depending on the output device being used; for example, the screen version can be quite different from the printed version, so authors can tailor the presentation appropriately for each medium.
