Restart animation in CSS3: any better way than removing the element?

No need in timeout, use reflow to apply the change:

function reset_animation() { var el = document.getElementById('animated'); el.style.animation = 'none'; el.offsetHeight; /* trigger reflow */ el.style.animation = null; }

#animated { position: absolute; top: 70px; width: 50px; height: 50px; background-color: black; animation: bounce 3s ease-in-out infinite; } @keyframes bounce { 0% { left: 0; } 50% { left: calc( 100% - 50px ); } 100% { left: 0; } }

<div id="animated"></div> <button onclick="reset_animation()">Reset</button>

@ZachB's answer about the Web Animation API seems like "right"™ way to do this, but unfortunately seems to require that you define your animations through JavaScript. However it caught my eye and I found something related that's useful:

Element.getAnimations() and Document.getAnimations()

The support for them is pretty good as of 2021.

In my case, I wanted to restart all the animations on the page at the same time, so all I had to do was this:

const replayAnimations = () => { document.getAnimations().forEach((anim) => { anim.cancel(); anim.play(); }); }; 

But in most cases people will probably want to select which animation they restart...

getAnimations returns a bunch of CSSAnimation and CSSTransition objects that look like this:

animationName: "fade" currentTime: 1500 effect: KeyframeEffect composite: "replace" pseudoElement: null target: path.line.yellow finished: Promise {<fulfilled>: CSSAnimation} playState: "finished" ready: Promise {<fulfilled>: CSSAnimation} replaceState: "active" timeline: DocumentTimeline {currentTime: 135640.502} # ...etc 

So you could use the animationName and target properties to select just the animations you want (albeit a little circuitously).

EDIT

Here's a handy function that might be more compatible using just Document.getAnimations, with TypeScript thrown in for demonstration:

// restart animations on a given dom element export const restartAnimations = (element: Element): void => { for (const animation of document.getAnimations()) { if ( animation.effect instanceof KeyframeEffect && element.contains(animation.effect.target) ) { animation.cancel(); animation.play(); } } }; 

1. Implement the animation as a CSS descriptor
2. Add the descriptor to an element to start the animation
3. Use a animationend event handler function to remove the descriptor when the animation completes so that it will be ready to be added again next time you want to restart the animation.

HTML

<div id="animatedText"> Animation happens here </div> <script> function startanimation(element) { element.classList.add("animateDescriptor"); element.addEventListener( "animationend", function() { element.classList.remove("animateDescriptor"); } ); } </script> <button onclick="startanimation( document.getElementById('animatedText') )"> Click to animate above text </button> 

CSS

@keyframes fadeinout { from { color: #000000; } 25% {color: #0000FF; } 50% {color: #00FF00; } 75% {color: #FF0000; } to { color : #000000; } } .animateDescriptor { animation: fadeinout 1.0s; } 

Try it here: jsfiddle

You can also use display property, just set the display to none.

display:none; 

and the change backs it to block (or any other property you want).

display:block; 

using JavaScript.

and it will work amazingly.

If you have a class for CSS3 animation, for example .blink, then you can removeClass for some element and addClass for this element thought setTimeout with 1 millisecond by click.

$("#element").click(function(){ $(this).removeClass("blink"); setTimeout(function(){ $(this).addClass("blink); },1 // it may be only 1 millisecond, but it's enough }); 

If you create two identical sets of keyframes, you can "restart" the animation by swapping between them:

function restart_animation(element) { element.classList.toggle('alt') }

@keyframes spin1 { to { transform: rotateY(360deg); } } @keyframes spin2 { to { transform: rotateY(360deg); } } .spin { animation-name: spin1; animation-duration: 2s; } .alt { animation-name: spin2; } div { width: 100px; background: #8CF; padding: 5px; }

<div id=_square class=spin> <button onclick="restart_animation(_square)"> Click to restart animation </button> </div>

The Animation API gives you full control over when and what to play, and is supported by all modern browsers (Safari 12.1+, Chrome 44+, Firefox 48+, Edge 79+) .

const effect = new KeyframeEffect( el, // Element to animate [ // Keyframes {transform: "translateY(0%)"}, {transform: "translateY(100%)"} ], {duration: 3000, direction: "alternate", easing: "linear"} // Keyframe settings ); const animation = new Animation(effect, document.timeline); animation.play();

There is an answer on MDN, which is similar to the reflow approach:

<div class="box"> </div> <div class="runButton">Click me to run the animation</div> 

@keyframes colorchange { 0% { background: yellow } 100% { background: blue } } .box { width: 100px; height: 100px; border: 1px solid black; } .changing { animation: colorchange 2s; } 

function play() { document.querySelector(".box").className = "box"; window.requestAnimationFrame(function(time) { window.requestAnimationFrame(function(time) { document.querySelector(".box").className = "box changing"; }); }); } 

On this page you can read about restarting the element animation: Restart CSS Animation (CSS Tricks)

Here is my example:

<head> <style> @keyframes selectss { 0%{opacity: 0.7;transform:scale(1);} 100%{transform:scale(2);opacity: 0;} } </style> <script> function animation() { var elm = document.getElementById('circle'); elm.style.animation='selectss 2s ease-out'; var newone = elm.cloneNode(true); elm.parentNode.replaceChild(newone, elm); } </script> </head> <body> <div id="circle" style="height: 280px;width: 280px;opacity: 0;background-color: aqua;border-radius: 500px;"></div> <button onclick="animation()"></button> </body> 

But if you want to you can just remove the element animation and then return it:

function animation() { var elm = document.getElementById('circle'); elm.style.animation=''; setTimeout(function () {elm.style.animation='selectss 2s ease-out';},10) } 

While still not ideal you could just restate your @keyframes with a different name, then just change the animation name when you want to run it again. This has the benefit of not needing JS in some use cases, like on hover or focus, etc:

@keyframes animate { 0% { opacity: 0, } 100% { opacity: 1; } } @keyframes animate_again { 0% { opacity: 0, } 100% { opacity: 1; } } div { animation: animate .2s ease-in-out; } div:hover { animation-name: animate_again; } 

I found out a simple solution today. Using the example provided in this answer, you can just append the element again to the body:

function resetAnimation() { let element = document.getElementById('animated'); document.body.append(element); }

#animated { position: absolute; width: 50px; height: 50px; background-color: LightSalmon; animation: bounce 3s ease-in-out infinite; } @keyframes bounce { 0% {left: 0;} 50% {left: calc(100% - 50px);} 100% {left: 0;} }

<!DOCTYPE html> <html> <head> </head> <body> <div id="animated"></div> <button onclick="resetAnimation()">Reset</button> </body> </html>

Using Chrome's developer tools, the append does not actually append the element to the body and just replace it, probably because the same reference to the element is used.

setInterval(() => { $('#XMLID_640_').css('animation', 'none') setTimeout(() => { $('#XMLID_640_').css('animation', '') }, 3000) }, 13000) 

Create a second "keyframe@" which restarts you animation, only problem with this you cannot set any animation properties for the restarting animation (it just kinda pops back)

HTML

<div class="slide"> Some text.............. <div id="slide-anim"></div> </div><br> <button onclick="slider()"> Animation </button> <button id="anim-restart"> Restart Animation </button> <script> var animElement = document.getElementById('slide-anim'); document.getElementById('anim-restart').addEventListener("mouseup", restart_slider); function slider() { animElement.style.animationName = "slider"; // other animation properties are specified in CSS } function restart_slider() { animElement.style.animation = "slider-restart"; } </script> 

CSS

.slide { position: relative; border: 3px black inset; padding: 3px; width: auto; overflow: hidden; } .slide div:first-child { position: absolute; width: 100%; height: 100%; background: url(wood.jpg) repeat-x; left: 0%; top: 0%; animation-duration: 2s; animation-delay: 250ms; animation-fill-mode: forwards; animation-timing-function: cubic-bezier(.33,.99,1,1); } @keyframes slider { to {left: 100%;} } @keyframes slider-restart { to {left: 0%;} } 

Note that with React, clearing the animation like this, a codesandbox I found helps.

Example I used in my code:

function MyComponent() { const [shouldTransition, setShouldTransition] = useState(true); useEffect(() => { setTimeout(() => { // in my code, I change a background image here, and call this hook restart then animation, // which first clears the animationName setShouldTransition(false); }, timeout * 1000); }, [curr]); useEffect(() => { // then restore the animation name after it was cleared if (shouldTransition === false) { setShouldTransition(true); } }, [shouldTransition]); return ( <div ref={ref2} style={{ animationName: shouldTransition ? "zoomin" : "", }} /> ); }
