HTML
The HTML page type allows you to hand-code the content area of your site in a simple mono-spaced code editing view. Your HTML can be as simple or complex as your knowledge of hand-coding, or you could use it to paste in embedded code such as YouTube clips and Google maps.
If you want to create an HTML page that retains the theme of the other pages in your website, be sure to leave the ‘Apply Theme’ checkbox located in the ‘Page’ tab of the Page Inspector selected. Unticking this box will remove all the theme layout from the page, giving you an entirely blank canvas to start from scratch.

Figure 1: The HTML Page
Note: You can enter anything into the HTML page type, including Javascript, CSS, PHP and more. Just remember that the page’s extension needs to reflect the content on the page, so be sure to check that the Page Inspector has been set up correctly. You should also check, if you're using PHP, whether your web host supports PHP as some hosts (including Apple's MobileMe service) do not support PHP.
