The cubic-bezier() values here are fundamentally different than the original ones

[tombigel]

After implementing some animations passed to us by our designers using the values from the named animations in easings.net we found some differences, after some investigations we discovered that the values we used from easings.net were not the same values used in places that uses the Penner math functions or the original cubic-bezier() values from http://robertpenner.com/easing/ and https://matthewlein.com/tools/ceaser

Are you saying that there is a difference between JS and CSS easings?

Can you show an examples before/after?

Ok, I did my research and I might be wrong 🙈

In my defense - The old school easing references (Caesar) have certain values, PostCss (which is linked to by easings.net) uses these values too)

But - the values in easings.net seems to be closer to the output of the math functions and to the GSAP implementation (which is my original reference)
