Layout
Layout is a core part of HTML. In this case file you'll learn what it is, why it matters, and how to use it in real code.
Understanding layout well means you can read other people's HTML code with confidence, and avoid the most common beginner mistakes in this area.
Key points:
- What layout means in the context of HTML
- A minimal example you can run or read in the playground on the right
- A common mistake to avoid when working with layout
<!-- HTML: Layout -->
<!doctype html>
<html>
<body>
<h1>Layout</h1>
<p>Edit this code and press Run to see it live.</p>
</body>
</html>
Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for layout.
