A navigation bar (also known as a links bar) is a sub region of a web page that contains hypertext links in order to navigate between the pages of a website. Usually navigation bars on websites are one of the least interesting things someone can find on a website. Usually, it’s plain text naming the categories or the pages the website has. It is not enhanced by graphics, by attractive patterns & textures, or by awesome realistic characters which would invite you to browse that page.
