HTML (HyperText Markup Language) is a page-description language. HTML
supports text, graphics, and other resources, along with the instructions
for presenting these elements in a browser. HTML focuses on multimedia
presentations and delivering applications that can run on the client's
processor.
Tags in HTML indicate instructions. A browser can read any HTML tag that its interpreter has been programmed to recognize; there is, of course, a lot of industry effort dedicated to creating a standard HTML convention that HTML authors can expect to work regardless of the browser a user is using.
