Because of the scope and complexity of the CSS3 efforts, the specification has been organized into multiple modules. Previous editions of the CSS specification were written as single entities, but with so much more being added to CSS3 it made sense to bring certain sections of the spec online as modules. That way, a spec could be developed, ratified, and implemented more quickly than if everything had to be in place in a single document. These modules are organized into specific topics such as color, media queries, paged media, text, and multicolumn layout.
