In this chapter, we gave you an overview of CSS. This is not a complete reference but we did include the most frequently used and useful CSS properties that should be supported by all browsers. We did not include (on purpose) some of the newer ones that were introduced in CSS3. One important new CSS feature that will be introduced in the second part of this book will be media queries. This is essential for building responsive designs, but this topic earns at least one chapter of its own.

So far, we have learned two languages we need to create websites: HTML and CSS. Without further delay, we now move on to the next one, a true programming language: JavaScript.
