Thank you for the prompt reply.
I use firebug to do just that. However, some of the styles for elements used are not totally obvious in widgets like Accordion.
I was thinking that a diagram that explicitly pointed to style and element that the process would be much quicker for the developer. For example it took me some time to discern exactly which element of the header was responsible for padding the text.
A diagram would have pointed me to the style immediately.
