# CKEditor Sample — Producing HTML Compliant Output

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)' }
    			}

    		// More definitions follow.
    	});
