@hafriedlander @normann Agreed that we should stay within the selector "scope" for class-based selectors. Although in practice it makes little difference at the moment, as it would be strange to have multiple $('.cms-content') or $('.cms-container') elements in a single DOM tree. Hamish, what's your feeling about making the toplevel elements ID-based instead? (which would speed up selectors).
