This tutorial introduces you to the basic features and language (the syntax) for Cascading Style Sheets (CSS). You use CSS to change the look of a structured document, such as a web page. The tutorial also includes sample exercises you can try on your own computer to see the effects of CSS and features that work in modern browsers.
The tutorial is for beginners and anyone who would like to review the basics of CSS. If you have more experience with CSS, the CSS main page lists more advanced resources.
What you need to get started
- A text editor
- A modern browser
- Some experience working with a text editor and browser
Although the exercises can help you learn, you are not required to complete them. You can simply read the tutorial and look at the pictures.
Note: The tutorial covers how CSS works with color. It will be easier to complete these sections with a color display and normal color vision.
