Learning HTML and CSS is hard, but it doesn’t have to be. This 14-chapter tutorial is one of the friendliest HTML and CSS guides on the Internet. We’ll walk you through everything from selecting a good text editor (which is surprisingly important) to building full-fledged, professional-quality web pages from scratch.

We designed HTML & CSS Is Hard to be the only introduction to HTML and CSS that you’ll ever need. If you put in the effort to read every section and write every code snippet, this tutorial has the potential to replace hundreds or even thousand of dollars worth of online courses and live training.



HyperText Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript are the languages that run the web. They’re very closely related, but they’re also designed for very specific tasks. Understanding how they interact will go a long way towards becoming a web developer. We’ll be expanding on this throughout the tutorial, but the gist of it is:

  • HTML is for adding meaning to raw content by marking it up.

  • CSS is for formatting that marked up content.

  • JavaScript is for making that content and formatting interactive.

Think of HTML as the abstract text and images behind a web page, CSS as the page that actually gets displayed, and JavaScript as the behaviors that can manipulate both HTML and CSS.
