Fast forward 15 years, and creating a website seems like an endeavor best left to the professionals. But Mozilla, carriers of the old Netscape crown, wants to change that perception with Thimble, a web-creation tool that promises to make the act of creating a website easier than ever.

Thimble will show you exactly where the website is broken — a missing HTML tag, for example. Even though you’re doing light work, you’re doing that work on a complicated page. The whole process feels far more enjoyable than your usual tutorial, as if you’re learning by doing something important. Even if that something important is a map filled with a Minecraft pig, CatBread and a triple rainbow.

Aside from a basic page creation tool, Thimble has a number of interesting tutorials built in to teach you HTML, and by extension, how to create your own page. One of the tutorials, called “Hack a Map,” gets you started with some pretty advanced code. But the tutorial isn’t about learning the advanced code, it’s about learning the basic errors that are causing the page at the left to show up incorrectly.
