13.In word processing and desktop publishing, a style sheet is a file or form that defines the layout of a document. When you fill in a style sheet, you specify such parameters as the page size, margins, and fonts. Style sheets are useful because you can use the same style sheet for many documents. For example, you could define one style sheet for personal letters, another for official letters, and a third for reports.

14.The selector points to the HTML element you want to style.

The declaration block contains one or more declarations separated by semicolons.

Each declaration includes a CSS property name and a value, separated by a colon.

A CSS declaration always ends with a semicolon, and declaration blocks are surrounded by curly braces.
