How it works

                                          |     {$styles}/nav.css ]

When a directory of the website is requested by a client, the file index.php in that directory is served. The file index.php includes the file template. php that contains the structure of each page of this site. The template creates the HTML page using the following files.

• config.php in the base directory with the site's configuration information (e.g. various folder locations. main page title, description and keywords)
• page.php in the current directory with the page's title, description and keywords
• content.php in the current directory with the page-specific information
• sidebarmenu.php in the base directory with the structure of the sidebar menu; the contents of the sidebar menu consists of the sitemap contents

The presentation of the HTML page is determined by the following PHP, JavaScript and CSS files

• {$libphp}/date.js contains the PHP code to generate the 'Page last changed...' message (see Last Changed)
• {$libjs}/navigation.js contains the JavaScript code to create the site and page navigation menus and the page's table of contents (see Site Navigation)
• {$styles}/print.css contains layout rules for printing (FireFox: View>Page Style>Print)
• {$styles}/common.css contains the general layout rules
• {$styles}/toc.css detemines the layout of the table of contents
• {$styles}/nav.css detemines the layout of the site and page navigation menus
• page.css in the current contains layout rules that are specific to the current page
