CSS (aka Cascading Style Sheets) is one of the "big three" languages of the web. It's used to style text, images, and other page elements, and control their positioning on webpages. CSS saves time because you can change the look of everything on your page—or just one element or section—with a simple line of code. After you have mastered HTML, CSS is the logical next step.

CSS Fundamentals covers the basic concepts, terminology, and techniques you need to read and write CSS. It's for people who want a big-picture overview before taking hands-on courses. Author James Williamson explains how CSS affects text, borders, backgrounds, and images; how CSS works with HTML; and how the W3C's evolving CSS specification impacts designers. He also reviews some of the most popular CSS editors and frameworks and lists online tools and resources for further study.
