The commands for displaying text use their own language called Hypertext Markup Language, or HTML.

HTML is nothing more than a coding system that combines formatting information in textual form with the readable text of a document.

The browser reads the formatting commands and organizes the text in accordance with them, arranging it on the page, selecting the appropriate font and emphasis, and intermixing graphical elements. The HTML commands are set off by a special prefix (called tag) so that the browser knows they are commands and not plain text.
