alright!
so on your homepage, i saw the blocks with horizontal clip anim. Speed is at 800ms, which I guess is default.
So if you add that to your css it should do the trick:
.image-block-outer-wrapper.combination-animation-horizontal-clip .image-block-wrapper{
transition: -webkit-clip-path 3600ms cubic-bezier(.4,0,.2,1),clip-path 3600ms cubic-bezier(.4,0,.2,1);
}
.image-block-outer-wrapper.combination-animation-vertical-clip .image-block-wrapper{
transition: -webkit-clip-path 3600ms cubic-bezier(.4,0,.2,1),clip-path 3600ms cubic-bezier(.4,0,.2,1);
}
I set it to 3600ms so that the difference is obvious, for both horizontal and vertical clip animation. So you just have to change that value to change the speed.
Let me know if it work.
Cheers,
Fab
