👀 What You Will See

A dark, modern navigation bar with logo on the left, navigation links centered with 24px gaps, a CTA button on the right, and sticky positioning pinned to the top of the browser window during scroll.

🧪 Try It Yourself

  1. Add @media (max-width: 640px) { .nav-links { display: none; } } to hide navigation links on small mobile screens.
  2. Observe how the navbar layout automatically adjusts using Flexbox!

⚠️ Common Mistakes

  • Forgetting align-items: center: Causes logo text, link list items, and buttons to stretch vertically or misalign along the top edge.
  • Forgetting position: sticky; top: 0; requires top value: position: sticky will NOT stick unless an explicit threshold (e.g. top: 0) is specified.

💡 Real-World Usage

Flexbox navbars form the header foundation for SaaS landing pages, documentation platforms (like MDN), news portals, and e-commerce applications.
