What is CSS?

As mentioned in our section on HTML, web pages are made up of content (the words and images you see), styling (the layout and design), and interactivity (the ability to click, drag, and manipulate things on the page). The styling comes from CSS (Cascading Stylesheets).

CSS provides layout using its box model and other styling using colors, fonts, background images, and more. CSS is very full-featured and we will not cover all of it, but touch on the most important parts.
