First, we will learn the basics of web development, that is to say, HTML and CSS. What is HTML? HTML (Hyper Text Markup Language) is a markup language for creating a web page.

Because of this, CSS is usually learned after or in tandem with HTML (and often JavaScript). Codecademy offers courses ranging from one to 115 hours, depending on your goals and current skill level.
