A hyperlink is a word, phrase, or image in an HTML document which you can click to go to a new document or to another section within same document. Hyperlinks are found almost on all the web pages allowing users to navigate through the website. When you move the cursor over a hyperlink it changes its shape to a hand pointing at the links. Hyperlinks are generally called just "links". Default text hyperlinks are underlined and blue in color but these settings can be overridden by using CSS.
