CSS

CSS, like HTML, is essential if you want to work as a front-end web developer. In my opinion, it's a great idea to see HTML and CSS alongside each other through things like this HTML and CSS class. The book can teach you the basics of CSS, HTML, network development, and how they all draw together. If you need to become a nice front-end or back-end system developer, we recommend studying JavaScript. Learn the basics with a class like the intro to JavaScript class or the Interactive JavaScript session, and then progress to a more difficult level once you're comfortable with the language's fundamentals.
