1. Introduction to CSS 2.1 for HTML

• CSS stands for Cascading Style Sheets
• Styles define how HTML pages are displayed
• Styles let you separate presentation from content
• A single style file can be applied to multiple web pages
• Advanced: Styles can be manipulated by javascript
• The biggest problem with CSS is not really in CSS itself, but in browsers that don't completely support it (particularly IE). You must test your work in multiple browsers.
