How much do you know about HTML?

📘 Theory

What HTML Actually Does

HTML gives structure and meaning before any visual style or interactivity appears.

1

A browser needs to know whether a piece of text is a page title, a paragraph, a navigation link or a form label. HTML provides that meaning.

2

That meaning matters not only for the browser, but also for search engines and assistive technology.

🧪 Learn by doing

Example Guided Example: A Minimal Document Edit the title and the paragraph so the structure starts feeling familiar.

What is this?

I'm Cristian Eslava and I sometimes build websites so both you and I can learn and experiment. culTest

I made this in February 2026 to make learning easier for my students. The idea is to learn web development by practicing and to keep expanding the project with new topics, tests and challenges.

It draws inspiration from MDN, W3Schools, CodePen, Manz and many other web development references. I wanted to combine useful theory, runnable examples, challenges and the testing system I had already built for culTest. culTest
