Single Webpage

Throughout the website, the validity of a webpage can be checked using the W3C XHTML and CSS validation links at the bottom of each page:

  • Valid XHTML 1.1 Validate against W3C's XHTML 1.1
  • Valid CSS Validate against W3C's CSS 1.0

Alternatively, the W3C Quality Assurance group has released an online validation tool called Unicorn, at http://qa-dev.w3.org/unicorn/. It is currently in Alpha stage, so use with caution.

Whole website

The entire website can be checked for valid XHTML content (with the W3C validator), using the list below. Each list item presents a link that validates a unique page within the website, and the full list covers the entire website contents.

If your web-browser supports the "iFrame" object, clicking on this link will display the validation results directly into sub-frames for each item in the list.

Expert users can try clicking this link to run a JavaScript Asynchronous request (AJAX) that automatically checks all the web pages in the background. After a little while, the validation state for each page will be indicated directly in the list above (For now, this ONLY works on Firefox with the GreaseMonkey extension that enables off-site XMLHTTPRequest by overriding the default security settings).

Alternatively, there is an online multipage validation tool based on the W3C validator, at http://www.validator.ca/. This pretty much does the same job, except it actually takes much longer because it validates a greater number of pages based on the URL GET parameters used in this website (for controlling font size, colors, etc.). The tool basically follows every single link it finds in the website, whereas the validation tool specific to the Urakawa website works more "intelligently", based on the exact site map. The Urakawa validator will also return the exact W3C result, whereas there seems to be some differences with validator.ca. Check out their user-comments for more information.
