What is CSS?

CSS stands for Cascading Style Sheets
Styles define how to display HTML elements
Styles were added to HTML 4.0 to solve a problem
External Style Sheets can save a lot of work
External Style Sheets are stored in CSS files

Styles Solved a Big Problem

HTML was never intended to contain tags for formatting a document.

HTML was intended to define the content of a document, like:

This is a heading

This is a paragraph.

When tags like , and color attributes were added to the HTML 3.2 specification, it started a nightmare for web developers. Development of large web sites, where fonts and color information were added to every single page, became a long and expensive process.

To solve this problem, the World Wide Web Consortium (W3C) created CSS.

In HTML 4.0, all formatting could be removed from the HTML document, and stored in a separate CSS file.

All browsers support CSS today.
CSS Saves a Lot of Work!

CSS defines HOW HTML elements are to be displayed.

Styles are normally saved in external .css files. External style sheets enable you to change the appearance and layout of all the pages in a Web site, just by editing one single file!

Introduction to CSS2

This article is not meant to teach you Cascading Style Sheets. If you are looking for a CSS tutorial, you should start with the previous link or try the Free CSS Class. In this article you will learn the basics of CSS2 and how it differs from Cascading Style Sheets, level 1.

Cascading Style Sheets, level 2, supports all of the functionality of CSS1. This means that if you create a CSS1 style sheet, it will work in a user agent that understands CSS2. Plus, the way that CSS1 is written, if you write a CSS2 style sheet, and load it in a CSS1-only user agent, that agent will simply ignore the elements and properties that it doesn't recognize.


Differences Between CSS1 and CSS2

There are some really interesting differences between Cascading Style Sheets level 1 and level 2. CSS2 offers many new options for accessibility and use across various user agents. Positioning in CSS2 is more flexible and offers more options to the designer. Automated content allows developers to force the user agent to display specific content elements as well as the layout, look, and feel. Also there is support for special cursors in CSS2 as well as dynamic outlining.
