How 2 Manning books explain it

Web Design Playground

A style sheet stored in a separate CSS file and linked to an HTML document instead of being written inline or in a style element.

How it is used
Shares CSS rules across multiple web pages to keep their appearance consistent and reduce repeated maintenance.
How deep it goes
Explains file creation, CSS-rule syntax, link placement, four href locations, and cascade precedence; it does not detail stylesheet loading internals.
Examples
Demonstrates links to styles.css, css/styles.css, /css/styles.css, and a remote Google Fonts URL.
What you can do after
Apply it via the link element to attach a shared CSS file using local, root-relative, or remote URLs.

What you can do after
Build it from scratch by creating a .css file and linking it from an HTML head.
