4.5. Linking External Style Sheets

Style sheets are a convenient way to create a document with a uniform theme. With external style sheets (i.e., separate documents that contain only CSS rules), you can provide a uniform look and feel to an entire website (or to a portion of one). You can also reuse the same external style sheet across multiple websites. Different pages on a site can all use the same style sheet. When changes to the styles are required, you need to modify only a single CSS file to make style changes across all the pages that use those styles. This concept is sometimes known as skinning. While embedded style sheets separate content from presentation, both are still contained in a single file, preventing a web designer and a content author from conveniently working in parallel. External style sheets solve this problem by separating the content and style into separate files.
