In an exercise system, I want to make sure students are entering their CSS rules in the correct place. Is there any way, in PhantomJS, to know where a CSS style came from?
For example, I want to know that an element is red because that CSS property came from an external stylesheet called index.css and not from an internal stylesheet.

I'm not sure if this helps, but you can use the Javascript function to return the properties of a given object.
getComputedStyle(element, [psuedoElement..]) A very important piece of information to consider is that the returned style object is read-only, and is the complete collection of styles of the node. Ie, if you say "font: SomeReallyCrazyFont" on <body>, calling getComputedStyle on a child element which doesn't have any explicitly defined font will contain "SomeReallyCrazyFont" as it's font property.
