A document-formatting language derived from the Standard Generalized Markup Language (SGML), predominately used to create Web pages. The user’s browser interprets HTML commands and formats the page layout, fonts and graphics on the screen. One of the more powerful features of HTML is its ability to create hyperlinks that enable the user to navigate between documents and files with a single click. HTTP is also sometimes used for messaging attachments as a way of supporting rich text formatting across product boundaries.

HTML that is generated by a program or service is considered “dynamically generated HTML,” which has been confused with the Netscape and Microsoft technology called dynamic HTML (DHTML). These technologies offer client-side mechanisms for enhancing the capabilities of the Web browser and HTML documents. Dynamically generated HTML might contain DHTML, but they are not the same thing.
