Obviously you can look at the classes on generated markup to find out what classes are available for a given Ionic component.

But, is there any officially documented source for what’s available?

A good example is `ion-tab-button.tab-selected`. Super useful class for styling. Anyone know if there’s a better way than inspecting elements?
