The Building Blocks of the Web
Discover what websites are really made of — three languages working together.
Step 1 of 5
What is a website, really?
Every website you visit — Google, YouTube, Wikipedia, Instagram — is just a collection of text files that your browser downloads and turns into the visual pages you see. There is no magic. When you open instagram.com, your browser fetches a few files, reads the instructions inside them, and paints the result on your screen. Those files are written in three languages, and learning those three languages is what this entire course is about.
Think of it this way: Think of a website like a house. Before you can live in it, someone had to draw blueprints (the structure), choose the paint colors and furniture (the style), and wire up the electricity and plumbing (the interactive stuff). Websites work the same way — three different jobs, three different languages.
Web Standard
The web is built on open standards maintained by the W3C (World Wide Web Consortium) and WHATWG. This means anyone can build a website, and any browser can display it. No single company controls the web.
