Hyper Text Markup Language (HTML)

Introduction to HTML

HTML stands for Hyper Text Markup Language. HTML was invented by Tim Berners-Lee, who was then working as a computer and networking specialist at a Swiss research institute. He wanted to give the Institute’s researchers a simple markup language, which would enable them to share their research papers via the Internet. Berners-Lee based HTML on Standard Generalized Markup Language (SGML), an international standard for marking up text for presentation on a variety of physical devices.

An HTML file is a text file containing small markup tags. The markup tags tell the Web browser how to display the page An HTML file must have an .htm or .HTML file extension.

An HTML file can be created using a simple text editor like notepad or wordpad.
