A website header sits at the top of each page and serves a few very important purposes. This does more than provide a place for your logo; it is part of a consistent user experience that all good websites share. This section is usually consistent across all of the pages on the website, however, some designs give the home page a slightly different header appearance in order to draw attention to featured areas of the site.
