A fixed header is a design feature in which the header or navigation bar of a website is “fixed” in place and stays visible at the top of the page even as the user scrolls down.
It is important in web design because it provides a consistent and convenient navigation experience for users, making it easier for them to access the main sections of the website. A fixed header also helps to improve the overall user experience, as it reduces the need for users to scroll back to the top of the page to access the navigation menu, especially on longer pages.
Additionally, a fixed header can help to improve the visual balance and hierarchy of a website, by keeping the primary navigation elements consistently visible and accessible at all times. By incorporating a fixed header into their web design, businesses can improve the user experience, increase engagement, and support conversions.
