HTML (HyperText Markup Language) is a web programming language designed to create web documents or web pages. Based upon SGML (Standard Generalized Markup Language), HTML's basic concept involves the use of "tags". These "tags", "mark up" or alert the browser that the document contains hypertext so it can be interpreted and rendered as a web page document. All HTML documents consist of a mix and match of HTML "tags" and "regular" text. Tags only aid in describing the document content or text, and thus leave the actual appearance and layout decisions for a web browser to handle when the web page is rendered or opened.
HTML documents are plain-text files that can be created using any basic or high-level text editor, such as Notepad, TextPad, or Microsoft Word or any other HTML authoring program. When you create an HTML document, you must save it with a .html or .htm extension. By default, most text editors save documents with a .txt extension, which is not capable of being displayed by a web browser. The .html or .htm extension allows the document to be rendered and displayed by a browser.
Unfortunately for web designers, web documents are browser dependent; sometimes, different browsers display content differently. A document may look crisp and clean in Internet Explorer, but it may have a slightly different look in Netscape, or vice versa. Web page designers should make every attempt to create portable HTML documents that can be opened by many different web browsers while showing little or no visual differences. Reliable HTML web pages are created by following all syntax rules and understanding which tags are supported by all web browsers.
