how to i reverse a css animation without reversing the timing function?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

If have the following keyframe rule:



@keyframes bounceIn {
0% {transform:translateX(0);}
60% {transform:translateX(18rem);}
100% (transform:translateX(15rem);}
}


And then add it to an element like this:



.myDiv {
animation: bounceIn .5s ease;
animation-direction: reverse;
}


Then the timing function gets reversed too. Is there a way to avoid the timing function from going in reverse, or is there a timing function that is the reversed of ease that i can use?



Im interested in this because, otherwise i would have to write 2 @keyframe rules in order to get the reversed animation but with ease as a timing function going both ways.



Thanks.

          or

          animation-direction: alternate;

            Wouldnt this reverse the timing function too? What if a just want to use the keyframe once, but in reverse - but without reversing the timing function?

          reverse is an essential tool of preventing code duplication, however with the timing function behaving differently it is less useful than it could be.



          The solution is to find such a timing function that would act as the inverse of the original timing function



          .myDiv {  
          animation: bounceIn .5s inverse(ease) reverse;
          }


          Of course there is no such construct as inverse(ease) but all timing functions being cubic bezier functions, we need another cubic bezier that will behave like the original when interpreted in reverse.
          The definition for the built-in timing functions can be found in the W3C spec



          e.g. ease is cubic-bezier(0.25, 0.1, 0.25, 1).



          Denote that as cubic-bezier(A, B, C, D).



          The inverse of ease will be a cubic-bezier(1-C, 1-D, 1-A, 1-B) which becomes cubic-bezier(0.75, 0, 0.75, 0.9)



          Use that in your code



          .myDiv {  
          animation: bounceIn .5s cubic-bezier(.75, 0, .75, .9) reverse;
          }


          Interestingly, the inverse of the ease-in-out gets you the same ease-in-out, so if you want a timing function that behaves exactly the same when interpreted in reverse, use that one.

            reverse is an essential tool of preventing code duplication, however with the timing function behaving differently it is less useful than it could be.



            The solution is to find such a timing function that would act as the inverse of the original timing function



            .myDiv {  
            animation: bounceIn .5s inverse(ease) reverse;
            }


            Of course there is no such construct as inverse(ease) but all timing functions being cubic bezier functions, we need another cubic bezier that will behave like the original when interpreted in reverse.

            e.g. ease is cubic-bezier(0.25, 0.1, 0.25, 1).



            Denote that as cubic-bezier(A, B, C, D).



            The inverse of ease will be a cubic-bezier(1-C, 1-D, 1-A, 1-B) which becomes cubic-bezier(0.75, 0, 0.75, 0.9)



            Use that in your code



            .myDiv {  
            animation: bounceIn .5s cubic-bezier(.75, 0, .75, .9) reverse;
            }


            Interestingly, the inverse of the ease-in-out gets you the same ease-in-out, so if you want a timing function that behaves exactly the same when interpreted in reverse, use that one.
