Eg. font-weight:bold to font-weight: 100 Transitions fire when used values change, but operate over computed values (currently, at least). Thus, as long as the keyword turns into a transitionable value at computed-value time, it's transitionable. 'font-weight' is a particularly weird example, because it doesn't *really* have numeric values - the "numbers" are actually playing the role of keywords. Thus, if you tried to transition from "font-weight:100" to "font-weight:200", all the values except the start and end would be invalid. This is why there's an issue at the 'font-weight' property in the "Transitionable Properties" table saying "It's not that simple". ~TJ
