Quoting the spec: "A frames timing function is a type of timing function that divides the input time into a specified number of intervals of equal length, each of which is associated with an output progress value of increasing value. ... This makes it suitable, for example, for using in animation loops where the animation should display the first and last frame of the animation for an equal amount of time as each other frame during each loop." See the spec link for examples.

this was about to ship in M60 but reverted due to unresolved issues over naming https://github.com/w3c/csswg-drafts/issues/1301 Ultimately, the frames() timing function was removed from the spec in favour of steps() and so frames() was removed from Chromium in https://crbug.com/935526. frames() was never shipped in Chromium.
