A navigation bar is a group of links that helps people move between important parts of a website. It is like the signs at a station that point toward the exits, platforms, and services.
It often appears across the top of a page, with links such as Products, Resources, and Contact. On a small screen, the same links may be gathered behind a menu button.
Keep the choices few and name them clearly. A navigation bar is for moving to another place, not for running every action the website offers.
