Question: [jQuery UI](http://jqueryui.com/) has some nice convenient CSS styles for alerting and highlighting. I can see it at [the themeroller site](http://jqueryui.com/themeroller/) -- look on the right hand side. Is there a Javascript interface to these styles? Do we use hard-coded CSS? Where is this documented?

Is there method list, a cheatsheat, or anything other than the interactive docs on jQuery UI?

Answer: 
Apply the appropriate CSS classes for the desired interaction cue from the [UI/Theming/API](http://jqueryui.com/docs/Theming/API#Interaction_Cues) page: **.ui-state-highlight** for highlight and **.ui-state-error** for error. You can do it statically or use `.addClass('ui-state-highlight')` or `.addClass('ui-state-error')` to do it dynamically.
They are just CSS styles. You can apply them on the backend, or apply them using .addClass().
