I'd like to make some features of my notebooks responsive to some properties of styles in the active stylesheet. Is there a way to do this? I can't seem to get anything out of StyleData. What I'm looking for is something of the form
StyleData["SomeStyle", "FontName"]
StyleData["SomeStyle", "FontSize"]
etc.
Are there functions or settings I can use to programmatically get information about properties of a style?

Default.nb). If necessary, choose a style from the "Choose a style" drop-down menu. Select the now-displayed cell named after that style. Now use the Option Inspector, either browsing for what you want in the outline hierarchy or else by using the Search box in the Option Inspector. – murray Nov 13 '12 at 21:59
