It would be handy if easings.net gave an example for Android.
The bezier easing functions can be easily created in Android (as Interpolators) by using the PathInterpolatorCompat method here:
PathInterpolatorCompat.create(x1, y1, x2, y2)
We should add <a href="/ru" rel="alternate" hreflang="ru"
for each language in footer to help Google see another languages (Google will not detect redirect by <select>
)
Of course, we could hide them when JS will be loaded.
Hi I noticed that the site didn't have a translation for Hindi language and If you want I can translate it for you and submit a PR so let me know if you want that.
Easings non available with css transition / cubic bezier (bounce/elastic) should be proposed in css animation (@Keyframes).
Hi,
I use your page a lot as a reference for CSS easings, they add more feel to just about any UI animation.
I find myself selecting and copying the blue cubic-beizer(...)
text a lot... There are awesome buttons to preview the easing for different animations, would it be possible to add a small button that copies the CSS easing function to your clipboard?
For those that don't like installing CSS plugins that transform easings automatically, this website is godsent.
That would be nice to have the javascript function for each easing mode.
for instance:
/**
* @param x input [0;1]
* @return eased input [0;1]
*/
function linear(x) {
return x;
}
of course for thing like bounce effect ease value may leave the [0;1] range.

The problem is that we need to create a right-to-left design (mirror design). You can try to use RTLCSS tool for that.
Is the easings.net site down?
Dark/Light theme doesn’t explain how to works.
This is a weird issue. While the easeBack functions (in/out/inout) seem to work on the front page (dot preview), they don't work when you try to view the dedicated page for it. The transition works, but the element will stay on position 0 (both in the beginning and the end) where the math function produces negative numbers (the "back" part).
This happens on both safari for mac and iOS.
What is even more weird, is that the very same function on cubic-bezier.com works perfectly.
I'd just like to express my gratitude towards this repository. Easing functions should be simple and you've achieved that goal.
Feel free to close the issue and tell me off.
Now it can be not clear which easing can be done in CSS. There can be few solutions:
Right now on the slick we change background
and invert color: white → black
on Open Source
button.
Unfortunately, color inverting make too much noise. I think we should just background.
Hey, I really like the idea behind easings.net. Thanks for the website.
I have an idea that maybe would be useful for the project. It would be great to have a short list of real life examples for each curve.
For example for easeOutQuad curve the simplest example is animation for removing an item from the list. Like this:
https://stackoverflow.com/a/41223246/10558733
https://codepen.io/chriscoyier/pen/ozlJK
A list of links to examples hosted on codepen might works for this.
What do you think?
This is more curiosity than anything. I noticed that the cubic-bezier()
presets in Chrome DevTools are different from the values here.
For example, this is what Chrome DevTools suggests for Out - Cubic
:
And this is what Easings.net's easeOutCubic
looks like:
Although the values look quite different, I compared them in DevTools, and the resulting curves are very similar. But, not exactly the same.
I find this rather strange since Google themselves reference and recommend Easings.net here:
https://developers.google.com/web/fundamentals/design-and-ux/animations/choosing-the-right-easing
My understanding was that easing functions were predefined mathematical equations, not open to interpretation. So how is it that these can differ?
Hi. I needed a set of easing equations for an MIT licenced Unity project. I grabbed these and ported them to C# before I spotted that this was GPL 3.0
I did a quick Github search and I can find several MIT licenced repos that have the same equations with the same names so I'm hoping that your copyright isn't on the actual formulae and names themselves.
I can redo the port from another source but I'd rather not - so I thought I'd check with you.
The project that makes use of them is here: https://github.com/IxxyXR/Polyhydra-upm
and the ported code is here: https://github.com/IxxyXR/polyhydra-upm/blob/master/Packages/Polyhydra/com.ixxy.polyhydra/Conway/Runtime/Easing.cs
Happy to add copyright/credits or anything you request - I just don't want to change my licence to GPL. I'd rather redo the port from another source if that's required.
For example:
easeInCirc
the value is cubic-bezier(.600, 0.040, 0.980, 0.335);
easeInBack
the value is cubic-bezier(0.600, -0.280, 0.735, 0.045);
Note that in first one there have no zero before dot in the first number, and the second one have.
Also, why those CSS values are so unoptimized?
Like you could make the transition: all 600ms cubic-bezier(0.600, -0.280, 0.735, 0.045);
can be shorten to transition: all .6s cubic-bezier(.6, -.28, .735, .045);
without any impact on readability.

It would be cool if you could provide the bezier functions for each easing:

Use this site almost daily. Love it guys.
I might be in the minority here... but I like light themes more than dark themes. I saw that the site switched over to a dark theme. I could possibly work on this feature, but would it make sense to add a lightbulb or something at the bottom of the page to toggle between each?
Hi
There are more easing type and easing function in DOTween. Like "Flash" easing type. It is an open source project. You can see the easing Code in this url: https://github.com/Demigiant/dotween/blob/90093a5c775ea22c9b3a2c828557f22a743c2589/_DOTween.Assembly/DOTween/Core/Easing/EaseManager.cs
Thanks.
Hi,
The small bubble in the last row goes from transparent to color.
In the other rows it goes from white/opaque to color.
Thanks
We should put language redirect to <head>

Using the Math function for easeOutBack: https://easings.net/#easeOutBack
function easeOutBack(x: number): number {
const c1 = 1.70158;
const c3 = c1 + 1;
return 1 + c3 * pow(x - 1, 3) + c1 * pow(x - 1, 2);
}
console.log(easeOutBack(0))
results in 2.220446049250313e-16
whereas it should be 0
If the calculation is correct then a simple conditional to return 0
when x === 0
would be necessary.
Is this JS?
Is this CSS?
How I use this?
What it is applicable to?
Example codes?
I just integrated all the TypeScript functions into a class, and noticed that for easeOutCirc
throws an error for sqrt
, as it should be Math.sqrt
. Super small issue, but might be nice to fix 😅
I found a bug in Safari(Version 13.0.2) when active animation on the third item of the charts group isn't working.
The problem is that 'will-change' should optimize the opacity animation and it does break somehow animation in Safari. I have changed styles from will-change: top, opacity;
to will-change: top;
to get it fixed.
This issue happens only in Safari so far.

This site is fantastic, and I'd love to use the easing function TS snippets in an MIT licensed project. Is there any chance that the function snippets (not the whole website) could be MIT, Apache, CC, or public domain?
It's not hard to find permissively licensed implementations for all of these, but it'd be nice to just copy straight from this site.

cubic-bezier(1/3, 0, 2/3, 1/3)
yields equivalently quadratic curve y=x^2
as the TypeScript code in math function section explains.
how about to use corresponding cubic-bezier(0.33, 0, 0.67, 0.33)
for easeInQuad?
also cubic-bezier(0.33, 0.67, 0.67, 1)
for easeOutQuad.
i hope this would help us.
I thought it was a little disappointing that the easing function you want to learn more about isn't used as the page transition.
It would be neat to add some jQuery magic in to allow for this!
the visualization for easings is really useful, but needing to look up the equations how to implement them elsewhere is kind of missing the point.
It would be cool if there were code snippets for supported easings, for example under the images comparing linear with the easing function.
Usually I look at http://www.gizma.com/easing/ for reference, but I like the visualization of easings.net better. However because the code snippets on the other site are very easy to all see and copy, I usually go there instead.
Maybe it should be written more as pseudo-code with better variable names or just pure math equation though to be better understandable to everyone.
Make links to http://cubic-bezier.com/ from selected easing.
Also, is it really neccessary, to edit cubic bezier?
I am mostly interested in the easing styles that are supported by CSS. Could some sort of logo, color, or badge be added to the front page to denote that a particular easing function is supported without using @keyframes
?
Using Firefox in OSX, I'm trapped on your page without the ability to navigate backwards.
Steps to reproduce:
there are extra unused parameters and incorrect variable (re)declarations in some equations. The result is in fact inconsistant.

you can note that all functions have to perform
There are too many parameters in all "easing" functions (making them not so easy to use) !
This could be avoided by passing a single normalized parameter t in 0..1, (and optional parameter s) so that all basic ease functions are also returning normalized values in 0..1 (possibly with external sweep in the middle near the two ends, if the easing is "amortized" on both ends.
As well the two parameters b and c are not so convenient: practical use prefer using start and end values directly (where b = start, c = end-start) for describing animations.
Ideally, there should be a clean way to control the maximum sweeping, not jsut for ease[In/Out]Back, but also ease[In/Out]Elastic (which should then use the "s" parameter too.
In the current implementation of ease[In/Out]Back, there's an internal variable "s" but it is incorrectly used and finally voided, producing the same value as the simplified equation above where the specific value of internal variables s and p are fixed, so that the formula reduces to a "sin(x + pi/2)" equivalent to a simpler "-cos(x)" (as written above).
I wonder if this behavior was the use of the old parameter x (always passed as null and taking needless memory and stack). This is probably an old bad design of jQuery's easings (which originally only defines the "linear" and "swing" modes, "swing" being an alias for the OutQuad method (find for implementing very "reactive" UI buttons, but not for realistic animations, especially for scenes in 2D/3D emulating normal physics, including in games)... Only the linear and quadratic curves are really realistic, quadratic to emulate objects falling down due to gravity. The elastic and bounding moves is not well suited because of arbitrarily fixed parameters. Even the existing bouncing is not realistic because it uses an infinitely hard surface and has no segment of elastic deceleration near the bounding surface (thing about how balls are bouncing on a surface: they are deformed and the surface is also deformed, both elastically, or sometimes semi-elastically (e.g. on non-compacted natural ground where this leaves a hole, and where a part of the energy is absorbed and not entirely reflected even on hard surfaces, e.g. when bouncing on a sand surface, or on water, sometimes even entering within water; another part is dissipated as temperature without "moving" any fragment of the bouncing surface, except temporarily, and another part of the energy creating "waves" around the impact and absorbing a lot of the energy but not as significant temperature elevation).
Note that .animate(...) can be chained in a queue (jQuery creates and uses a default queue for each animatable object) using .animate(...).animate(...).
jQuery provides unnecessary callbacks for start and end events, which should be just inserted in the queue as an .animate(...) with duration=0. Animations in jQuery still required more work.
As well easings should be easier to do for 2D/3D animations using Bezier splines curves: instead of just using static values (min and max for t=0 and t=1 respectively, we should be able to link two easings for each coordinate in 2D, or three easings in 3D).
As well the easings above should have a way to specificy the parameters fixing the differential speed (negative or positive) at start and end; the functions above have a single fixed value for start and end speeds with limited values: 0, 1 or infinite (this is fixed at end only for easeIn* and easeOut*, and arbitratrily fixed at both start and end on the same value for easeInOut*, splitting the range arbitrarily in two mirrored parts exactly in the middle of time range)...
Animations using quadratic, cubic or elliptic beziers cannot be designed so simply with basic bezier control points or radii or focal points for elliptic curves given in their coordinate space: we have to predecompose the Bezier to create a parametric equation based on time and measuring the length along the Bezier or ellipitic curve to compute the final coordinate. So these easings are mostly fitted only for 1D effects.
Outside jQuery, in the CSS or SVG or OpenGL working groups, there are ongoing works on what is needed to describe a 2D or 3D scene: none of these easings are usable, except the "linear" one for moves along small arcs. Animations are then just basic designs made for 1D
It would be good to get your thoughts on good easing practice for zooming out.
While ease-in/out for an object on a path through a 2D surface is straightforward, zooming is another story.
Zooming in on a 2D scene works well with linear. But zooming out, even with typical ease-out, looks too accelerated.
