Validating your HTML

An important step in HTML creation is validating your HTML. The offical standards for html are defined by the World Wide Web Consortium. PG requires that all HTML files submitted be valid according to their validator.

Another useful tool is HTML Tidy, which you can download to run on your own system. Tidy can be downloaded from Sourceforge. (However, do use caution if you are using Tidy to format your html, as it can, in rare instances, have unintended side-effects.) To directly download the file click here (or here if you're reading this sometime after April 2008 and want to check for more recent versions).

Latest versions since 2015 are available here, HTML Tidy version 5.8.0 is the latest as of July 2021.

Finally, you should check every link manually to make sure they all work, and check that all your illustrations are linked correctly.
