Write real HTML and watch the page take shape beside your code. Short lessons, a project you keep, and an AI tutor that can read what you wrote.
Every web page you have ever seen starts as HTML. It is the layer that says this is a heading, this is a paragraph, this is a link, this is an image - the structure and meaning underneath everything else. Learn it and the web stops being magic and becomes something you can take apart.
It is also the most satisfying place to begin, because the feedback is visual. You don't read output in a console; you watch a page assemble itself as you type.
With a live preview beside your code. Devpuff's HTML lessons render your markup as you type - add a tag, watch the page change. Automated checks confirm each requirement ("has an h1", "every image has alt text"), so you always know what's done and what's next. Hints unblock you without spoiling the answer, and Puff, our AI tutor, can read your actual code when you're properly stuck.
HTML Basics covers the core - elements, nesting, links, images, lists, and semantic structure - and ends with a personal homepage you build yourself, graded by real checks. Intermediate HTML then goes deep: real forms with the right input types, tables, audio and video, the meta and Open Graph tags that decide how your page looks when it's shared, and the accessibility details that make it usable for everyone.
HTML is half of the front of the web; CSS is the other half. It's the first course of the Frontend Development program, which continues through CSS into JavaScript and React - the standard route into frontend work. Every step of it starts free.
Not quite. HTML is a markup language - it describes the structure and meaning of a page rather than computing anything. That is exactly why it is the right first thing to learn. You get the full write-code-see-result loop with none of the logic errors, and everything you make is instantly visible.
No. Devpuff renders your markup in the browser as you type, side by side with your code. There is no editor to set up and no files to manage - you write a tag and watch the page change.
The essentials are small enough to be productive within your first sessions - headings, paragraphs, links, images, lists, and forms. Devpuff splits it into HTML Basics for the core and Intermediate HTML for the depth - tables, media, accessible forms, and the meta tags search engines and social cards read.
