Templates

Contents

Templates are the files which control how your WordPress site will be displayed on the Web. These files draw information from your WordPress MySQL database and generate the HTML code which is sent to the web browser. Through its powerful Theme system, WordPress allows you to define as few or as many Templates as you like all under one Theme. Each of these Template files can be configured for use under specific situations. More information on creating Themes can be found at Theme Development.
