1. Introduction

I assume you already know the whole markup system; if not, I recommend visiting the HTML course, and now you want to learn how to add styles.

Working with style sheets, or CSS, can be as deep as you are willing to dive. The basics are learned quickly (formatting, colors, borders...), and you will build a fairly decent website. But you will quickly notice limitations as soon as you get a little ambitious with the design. If your goal is to go further (animations, 3D, layout, responsive designs...) you will discover just how deep, and exciting, it can get. It depends on you, on how far you are willing to go. The possibilities are immeasurable.

Let's start by getting to know the syntax and how to integrate it with HTML.
