HTML(Hypertext Markup Language)
-is the set of markup symbols or codes inserted in a file intended for display on a World Wide Web
browser page. The markup tells the Web browser how to display a Web page's words and images for the user.
Each individual markup code is referred to as an element (but many people also refer to it
as a tag). Some elements come in pairs that indicate when some display effect is to begin
and when it is to end.
