Every way to learn

Read, listen, test yourself, ask the AI, or look up anything you've already covered. Every lesson meets you where you are.

Intro to Variables
Audio

A variable is a named container that stores a value you can reference later in your program.

In Python, you create one by writing the name, an equals sign, then the value you want to store.

The value can change over time - reassigning the name simply points it to a new value.

Why learn HTML with Coddy

  • Write HTML in your browser and see the rendered page side-by-side. No editor install, no setup. Every change you make to the HTML code shows up live, so the feedback loop is short.
  • Modern, semantic HTML: headings, lists, links, images, tables, forms, and semantic tags like <header>, <nav>, <main>, <section>, <footer>. The HTML you'd actually use to build a real website.
  • AI hints help you fix HTML mistakes - unclosed tags, broken attribute syntax, accessibility slips - without spoiling the answer, so HTML coding habits stick.
  • Free HTML certificate when you finish. A credible first step for web development, paired naturally with the CSS and JavaScript courses.

Frequently asked questions about learning HTML

Is HTML hard to learn?

HTML is one of the easiest things you can learn in tech. It's a markup language, not a programming language - you're labeling pieces of content (headings, paragraphs, links, images) rather than writing logic. Most beginners build their first real web page within the first hour.

How long does it take to learn HTML?

You can learn the core HTML tags and attributes in a few days of focused practice. Becoming comfortable with semantic HTML, forms, and accessibility usually takes one to three weeks. Pairing it with CSS and JavaScript to build full pages is then the natural next step.

Should I learn HTML before CSS and JavaScript?

Yes. HTML defines the structure of a page; CSS controls how it looks; JavaScript makes it interactive. Learning HTML first means you have something concrete to style and animate later. The HTML course is short on purpose so you can move on to CSS and JS quickly.

Is HTML a programming language?

Strictly speaking, no. HTML is a markup language used to describe the structure of web content. It has no variables, conditionals, or loops on its own. The actual programming on a web page comes from JavaScript, covered in a separate course.

Can I learn HTML online for free?

Yes. The interactive HTML course is free - lessons, coding exercises, a live HTML preview, and a certificate. Everything runs in the browser so you don't need to install any editor or tooling to get started.

Do I get a certificate after the HTML course?

Yes. Finishing the HTML course gives you a free certificate of completion. A verifiable proof point you can add to your resume or share on LinkedIn - usually as a step toward a fuller HTML, CSS, and JavaScript portfolio.
