Markup Validation Service

This Page Is Valid XHTML 1.1!

Tip Of The Day:

Care With Font Size

The document located at <http://%E7%B4%8D%E8%B1%86.w3.mag.keio.ac.jp/> was checked and found to be valid XHTML 1.1. This means that the resource in question identified itself as "XHTML 1.1" and that we successfully performed a formal validation using an SGML or XML Parser (depending on the markup language used).

To show your readers that you have taken the care to create an interoperable Web page, you may display this icon on any page that validates. Here is the HTML you should use to add this icon to your Web page:

    <p>
      <a href="http://validator.w3.org/check?uri=referer"><img
          src="http://www.w3.org/Icons/valid-xhtml11"
          alt="Valid XHTML 1.1!" height="31" width="88" /></a>
    </p>
    

Thanks to this code, you will be able to re-validate your Web page by following the link (click on the image), and we encourage you to do so every time you modify your document.

If you use CSS in your document, you should also check it for validity using the W3C CSS Validation Service.

If you would like to create a link to this page (i.e., this validation result) to make it easier to validate this page in the future or to allow others to validate your page, the URL is <http://qa-dev.w3.org/wmvs/ot/check? uri=http%3A%2F%2F%25E7%25B4%258D%25E8%25B1%2586.w3.mag.keio.ac.jp%2F> (or you can just add the current page to your bookmarks or hotlist).
