> Since it's already allowed in a more limited way, letting the dependent variable (progress) to go outside the 0..1 range shouldn't be much of a problem. Right, that part is fine. > For the independent variable (time), though -- I'd imagined we'd just use the section of the timing function between 0 and 100%, regardless of where the first/final knots are, extrapolating past the end knots with straight lines if necessary. What I'm more concerned about is when f(0) != 0 or f(1) != 1. There certainly used to be places where we assumed that. With step-start you can already have f(0) != 0 but only when the "before flag" is false. I recall that in the past that invariant proved useful but perhaps it's fine now. (It may have been when we were trying to chain timing functions together, or when we were trying to invert them in order to work out when to dispatch events -- but we don't do either of those things anymore). -- GitHub Notification of comment by birtles Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/229#issuecomment-491716926 using your GitHub account
