Keyframes

Introduction

The Keyframes example shows how to create complex multi-step animations in React using Motion's keyframes feature. With keyframes, you can define a sequence of values that your animation will progress through, creating rich and engaging animations.

Keyframes are simple to define, with an array syntax:

x: [0, 100, 100, 50]

This will animate the x property from 0 to 100, then back to 50.

Get started

Let's start with a basic square component:

export default function Keyframes() {
    return (
        <div
            style={{
                width: 100,
                height: 100,
                backgroundColor: "white",
                borderRadius: 5,
            }}
        />
    )
}

Let's animate!

Import from Motion

First, we'll import Motion:

import * as motion from "motion/react-client"

Now we can convert our square to a motion.div:

<motion.div style={box} />

Creating the keyframe animation

To create our complex animation, we'll use the animate prop to define arrays of values for different properties:

<motion.div
    animate={{
        scale: [1, 2, 2, 1, 1],
        rotate: [0, 0, 180, 180, 0],
        borderRadius: ["0%", "0%", "50%", "50%", "0%"],
    }}
    style={box}
/>

We can customise the animation by adding a transition prop:

transition={{
    duration: 2,
    ease: "easeInOut",
    times: [0, 0.2, 0.5, 0.8, 1],
    repeat: Infinity,
    repeatDelay: 1,
}}

The times array here adjusts when the timing of each keyframe occurs in the animation, where 0 is the start of the animation and 1 is the end. By default, keyframes are evenly spaced throughout the duration of the animation.

The repeat property makes the animation loop forever, and the repeatDelay property adds a 1-second pause between each loop.

1.card {2  transition: scale 200ms linear(3    0, 0.009, 0.036, 0.084, 0.157, 0.255, 0.378,4    0.522, 0.679, 0.832, 0.954, 1.029, 1.052, 1.038,5    1.011, 0.99, 0.984, 0.991, 1.001, 1.005, 16  );7}89.card:hover {10  scale: 1.2;11}

Conclusion

In this tutorial, we learned how to:

• Create multi-step animations using keyframe arrays
• Animate multiple properties simultaneously
• Control the timing of keyframes using the times array
• Create infinite animation loops with delays
