HTML documents are plain-text (also known as ASCII) files that can be created using any text editor. HTML stands for Hypertext Markup Language and is the computer language used to design web pages. HTML has been in use by the World-Wide Web (WWW) global information initiative since 1990. Once you understand the syntax of HTML and know how to write it, it's quite simply for you to create a HTML file. All you need is a simply text editor like Notepad on Windows, then you write your html code and save it with a (.html, .htm) extension. There is even simplier ways to create HTML files, such as using a software package like Macromedia Dreamweaver or Microsoft Frontpage. These packages automatically write the code for you and you can create a web page in a totally graphical interface with very little knowledge of HTML syntax and how to write it.
