What is HTML

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.
