CSS Compare is a Google Chrome add-on that adds a sidebar in the Inspect Element window that enables you to view various CSS properties of two different DOM elements.
You will be able to use CSS Compare for quickly finding small differences between two DOM elements that were supposed to have the same style.
CSS Compare is cross-platform and it works on Mac OS X, Windows and Linux.
