How do you apply such > concepts? At a guess timeLimit corresponds to 'active duration' and rationalValue corresponds to 'time fraction' in Web Animations terms. However, what Web Animations does here is beside the point. There may be more natural ways of reversing transitions that avoid inconsistencies and these can still be realised using the underlying Web Animations model by generating a separate reverse animation.
