W3 School Cascading Style Sheet Tutorial: www.w3schools.com/css/

• CSS stands for Cascading Style Sheets
• styles define how to display HTML elements
• HTML was never intended to contain tags for formatting a document; rather it is intended to define the content of a document
• when tags for formatting began to be added to HTML, CSS was created so that all formatting could be removed from an HTML document and stored in a separate CSS file

I have reviewed the rest the W3 CSS tutorial

I have reviewed the CSS Tutorial, starting with HTML and CSS

Hakon Lie and Bert Bos, Cascading Style Sheets, Designing for the Web. 2nd ed. Addison Wesley, 1999.

• a rule is a statement about one stylistic aspect of one or more elements
• a style sheet is a set of one or more rules that apply to an HTML document
• a rule consists of a selector and a declaration
• selector - link between HTML document and the style; specifies what elements are affected by the declaration
• declaration - part of the rule that sets forth what the effect will be
• a declaration has two parts
• part before the colon = property
• quality or characteristic that something possesses
• part after the colon = value
• precise specification of the property
• a selector may have may have more than one declaration
• identical selectors can be grouped together on one declaration
• the style sheet must be "glued" to the document in order to affect the HTML
