Header component: navigation, sticky behavior and accessibility

Learn how to design robust headers with branding, adaptive navigation, sticky behavior and visible keyboard focus so the top area of the interface stays useful instead of becoming visual clutter.

📘 Theory

A recommended structure

Brand, primary navigation and actions should form one clear hierarchy.

1

Use `` as the semantic container and place `` inside it for the main navigation region.

2

Group links into lists and keep secondary actions such as login or the main CTA visually separate from the primary navigation so scanning stays easy.

A sticky header without visual friction

Keep navigation visible without making the scroll experience feel heavy.

1

With `position: sticky` and `top: 0`, the header stays visible while still participating in the normal document flow.

2

Adding a solid or translucent background plus a bottom border or soft shadow helps preserve readability once content starts moving underneath it.

🧪 Learn by doing

Example Demo: responsive header A desktop-friendly horizontal header that compacts gracefully on smaller screens.

🏁 Challenges

Challenge Challenge: make the header sticky Turn the header into a sticky element with a top offset of `0` and a high stacking order.

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
