CodeHelp makes extensive use of external HTML. The site has one set of content pages for all Javascript enabled browsers but uses three sets of navigation pages which each make the best use of the particular browser required. This means that the site can fully implement stylesheets and DHTML without leaving some visitors behind. See the codehelp site for more information on external HTML

Stylesheets are particularly suitable as external links. Using a single file for all appropriate pages makes updating and amending the site simple. One change to the stylesheet file and all pages on the site could reflect the amendments without you having to alter any HTML or upload any of the HTML files themselves using FTP. The syntax is <link rel="stylesheet" href="URL" type="text/css"> The stylesheet file itself should be a plain text file with a .css extension contain only the text you would otherwise enter between the <style></style> tags. Only one stylesheet can be linked to any one HTML page. If, like CodeHelp, you use external HTML, you are allowed to link one stylesheet to the main page and a different one to the external content.

If more than one page uses the same functions (such as the one that loads some pages in new browser windows) the javascript code can be imported from an external text file - with the .js externsion - using the following syntax in the HTML document: <script language="Javascript" type="text/javascript" src="URL"></script> Remember to only include the javascript code otherwise contained within the <script></script> tags. (Comment markers in the external file <!-- and --> are optional.)
