HTML is an acronym for HyperText Markup Language. HTML was created in 1991 by Tim Berners Lee.
The term HyperText in HTML refers to the text that has reference to other text. A user can access the hypertext by clicking on the hyper links. The term markup language refers to combination of words and symbols which give instructions on how a document should appear on the web.
Therefore, HTML is a language that is used to create documents on world wide web (www). HTML is not a programming language, but it is a markup language. It is used to put text, images, graphics, audio and video to the web pages. It allows one web page to link to the other web page through hyperlinks. An HTML document has head, body, style sheet, script and frame set. The head contains information that is implemented by the browser or used by search engines. The body contains all the content to be displayed.
The style sheet defines how the document should appear on the browser, the script sets up interaction with the user using a simplified programming language and the frame set may divide the browser window into sets of smaller windows that can each hold it. A text editor is used to write the HTML code. An example of such a text editor is notepad. Tags are the most important part of the HTML. They are used to format the text, insert a graphic, image, audio video to the web page.
The HTML tags are written in angular brackets example <Tag>. Most of the tags are container that is they exist in pairs. For example <HTML> , </HTML>. <HTML> is an opening tag whereas </HTML> is a closing tag. It is important to close an opening tag to make in functional on the web. The HTML document is saved with .html or .htm extension.
