HTML files are saved in a standard text format and consists of tags used to define the structure of a webpage. The files can be opened and edited with a basic text editor but are typically opened by source code editors that come with features that make it easier for developers to code.

HTML source code is parsed by a web browser and is typically not seen by the user. If you want to view the HTML of a webpage, select "View Source" from the web browser's View menu.

Common HTML Filenames

index.html - The main, or index, HTML file that's loaded when a client Web browser requests a Web server directory. For example, when http://www.sampledomain.com/ is requested, the Web server loads http://www.sampledomain.com/index.html by default, unless it is configured to use a different file.

default.html - The index file often used by Windows Web servers such as Microsoft IIS.
