Hey, there! Look at our new WYSIWYG editor.

preClass #

Type: String Boolean

Default: false

This setting allows to set a predefined class for the pre tag. Example below, will make all code inside of pre tag to be highlighted, and have line numbers.

$R('#content', {
        preClass: 'prettyprint linenums'
});

});
