<style> with wrong mimetypeThis text will be green if the rule has been applied.
<style type="text/nonsense">
/*<![CDATA[*/
#testElement {
color: #00ff00;
}
/*]]>*/
</style>
Because style sheet contents must be of the mimetype text/css, standards-compliant browsers should not apply stylesheets with different mimetypes and will not apply this rule (so the text in the example block should be red in compliant browsers).
