This sample shows how to configure CKEditor to output valid HTML 4.01 code. Traditional HTML elements like <b>, <i>, and <font> are used in place of <strong>, <em>, and CSS styles.
To add a CKEditor instance outputting legacy HTML 4.01 code, load the editor using a standard JavaScript call, and define CKEditor features to use the HTML compliant elements and attributes.
A snippet of the configuration code can be seen below; check the source of this page for full definition:
CKEDITOR.replace( 'textarea_id', { coreStyles_bold: { element: 'b' }, coreStyles_italic: { element: 'i' }, fontSize_style: { element: 'font', attributes: { 'size': '#(size)' } } ... });
