Comments are used to write notes to yourself within an HTML document. They do not appear when a browser displays a Web page. Comments can also be placed around HTML code to turn that code off. HTML tags inside comments are not interpreted by the browser. Use <!-- --> tag to add HTML comment element in the web page.
