ui theme documentation

ui theme documentation


hello,
I've found the jQuery UI demos helpful for learning about the ui
widgets.
But what about the theme classes? I'd like to learn what CSS classes
are available and what they are good for.
A few that I understand how to use:
ui-widget: makes widget bigger
ui-state-default: applies default style to widget
ui-corner-all: adds corners to widget (but not on IE?)
ui-state-hover: highlights widget
And some others I've come across:
ui-helper-reset, ui-widget-content, ui-helper-clearfix, ui-widget-
header, ui-overlay, ui-widget-overlay, ui-widget-shadow
Is there documentation available for these classes?
