Right now if I want something to trigger an animation on a different element then that element must have a unique class name in order to only trigger that one instance. I need therefor the remove the current class, put a new one in and apply all the same styling all over. It would be much handier if I could also target an element by an ID name. Or be able to attach a sub class to it and target the full class string (for example "div-header red top")
With Interactions 2.0 you'll be able to target any element, whether it has one class or multiple classes/combo-classes.
