CKEditor requires JavaScript to run. In a browser with no JavaScript support, like yours, you should still see the contents (HTML data) and you should be able to edit it normally, without a rich editor interface.
This sample shows CKEditor configured to produce XHTML 1.1 compliant HTML. Deprecated elements or attributes, like the <font> and <u> elements or the "style" attribute, are avoided.
Editor 1: <p>This is some <span class="Bold">sample text</span>. You are using <a href="http://ckeditor.com/">CKEditor</a>.</p>
