Components

Components is a core part of Bootstrap. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding components well means you can read other people's Bootstrap code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

What components means in the context of Bootstrap
A minimal example you can run or read in the playground on the right
A common mistake to avoid when working with components

<!-- Bootstrap: Components -->
<!doctype html>
<html>
  <body>
    <h1>Components</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 components.
