27 This sample shows how to configure CKEditor to output valid
28 <a class="samples" href="http://www.w3.org/TR/html401/">HTML 4.01</a> code.
29 Traditional HTML elements like <code>&lt;b&gt;</code>,
30 <code>&lt;i&gt;</code>, and <code>&lt;font&gt;</code> are used in place of
31 <code>&lt;strong&gt;</code>, <code>&lt;em&gt;</code>, and CSS styles.
32 </p>
33 <p>
34 To add a CKEditor instance outputting legacy HTML 4.01 code, load the editor using a standard
35 JavaScript call, and define CKEditor features to use the HTML compliant elements and attributes.
36 </p>
37 <p>
38 A snippet of the configuration code can be seen below; check the source of this page for
