The header of a website is located at the top of each page and has several important purposes. In addition to displaying a website's logo, it helps create a consistent user experience that all good websites share.
Although the design of headers may vary from site to site, the core features that determine how a site is navigated and experienced remain the same. This section is usually consistent across all of the pages on the website. Still, some designs give the home page a slightly different header appearance to draw attention to featured areas of the site.
Overall, a good header makes your website easier to navigate, establishes your brand, and creates a consistent browsing experience throughout your website.
