How to toggle HTML/CSS animation on hover and on click

Question

I am having trouble trying to stop and start animation whenever I hover over the element or on click. This is my HTML element:

<div class='marquee'>
   <h1>Some Text</h1>
</div>

CSS:

.marquee {
    width: 80%;
    white-space: nowrap;
    overflow: hidden;
    box-sizing: border-box;
}

.marquee h1 {
    display: inline-block;
    padding-left: 100%;
    animation: marquee 15s linear infinite;
}

@keyframes marquee {
    0%   { transform: translate(0, 0); }
    100% { transform: translate(-100%, 0); }
}

Right now, the animation just goes on forever by default. How can I have it so that whenever I hover over or click on the h1 or the div, the animation will pause and resume accordingly. I'm assuming to pause/restart the animation on click, I would need a JavaScript function. Any help is appreciated.

@OmriAttiya I'm not using webkit so I don't think that'll solve it — Red Apple, Apr 04 '20 at 00:21
@RedApple you don't need the webkit prefixes anymore, but that's still the same, JS `style.animationPlayState` and CSS `animation-play-state`. — Kaiido, Apr 04 '20 at 02:28

You can use animation-play-state rule:

.marquee {
    width: 80%;
    white-space: nowrap;
    overflow: hidden;
    box-sizing: border-box;
}

.marquee h1 {
    display: inline-block;
    padding-left: 100%;
    animation: marquee 15s linear infinite;
}

.marquee h1:hover {
    animation-play-state: paused;
}

@keyframes marquee {
    0%   { transform: translate(0, 0); }
    100% { transform: translate(-100%, 0); }
}

<div class='marquee'>
   <h1>Some Text</h1>
</div>

Or with JS:

function stopAnimation(e){
   if (e.target.style.animationPlayState == ""){
     e.target.style.animationPlayState = "paused";
   } else {
     e.target.style.animationPlayState = "";
   }
}

.marquee {
    width: 80%;
    white-space: nowrap;
    overflow: hidden;
    box-sizing: border-box;
}

.marquee h1 {
    display: inline-block;
    padding-left: 100%;
    animation: marquee 15s linear infinite;
}


@keyframes marquee {
    0%   { transform: translate(0, 0); }
    100% { transform: translate(-100%, 0); }
}

<div class='marquee'>
   <h1 onclick="stopAnimation(event)">Some Text</h1>
</div>

That worked for hover! Thank you! I was wondering how to do this for onClick as well. – Red Apple Apr 04 '20 at 03:21
I update my answer – Hans Felix Ramos Apr 04 '20 at 03:28
Hi, So I'm using React so the div and the h1 are returned by a React component so I can't use "this" for the "stopAnimation(this)" for the onClick since that "this" would point to the whole React Component rather than just the h1. – Red Apple Apr 04 '20 at 03:37
On react the event is passed as deafult. you can use ` e.target` to get the element – Hans Felix Ramos Apr 04 '20 at 03:44
Hi, it doesn't work. Whenever my mouse leaves, it just resumes animation. – Red Apple Apr 04 '20 at 03:54

It works now. I removed "event" from ```onClick={this.stopAnimation}```. Thank you! – Red Apple Apr 04 '20 at 04:18
Not related to the question but I was wondering if you would know how to achieve this: once the animation is paused, I want to scroll through the text to reach the end, only on paused tho, on resume, there would be just the animation and no scroll. – Red Apple Apr 04 '20 at 04:36
That would be something different, and more JS code would be used. I imagine you are thinkhing in a drag event – Hans Felix Ramos Apr 04 '20 at 06:18
You can post it with a separate question. and putting some your code in react – Hans Felix Ramos Apr 04 '20 at 06:18

I would suggest using jquery to change the animation property.

$('.marquee').mouseenter(() => { $(this).css("animation: marquee 15s linear infinite"); } );

$('.marquee').mouseleave(() => { $(this).css("animation: none"); } );
