HTML (Hypertext Markup Language) is a mark-up or formatting language that is used by most graphical browsers. Text files are marked up with special codes called tags that tell the browser how to format the text. Tags in HTML are surrounded by the symbols < and >. Web pages are formatted using these tags and are called HTML files.
There are HTML tags for headings, font style and size, graphics, color, tables, lines, and many more elements you can include on a web page.
Hypertext refers to the use of text or graphics to link to another HTML document which can be on the same server or on any other server around the world.
There is an official HTML language which contains a specific set of tags that all browsers should recognize. New tags are added when a new specification comes out. Some browsers recognize tags that are not part of the standard.
