Issue with adding a new animation to the text

I have a text which appears when I run contrastShow function like this:
const contrast = document.getElementById("contrast");
function contrastHide() {
//sfxPlay(sfx.caption_hide);
contrast.classList.add("contrastHide");
contrast.classList.remove("contrastShow");
}
function contrastShow(text) {
contrast.innerHTML = text;
contrast.classList.add("contrastShow");
contrast.classList.remove("contrastHide");
}
contrastShow("This is the text");
setTimeout(() => {
contrast.classList.add("zoomIn");
}, 3000);
.contrast-container {
overflow: hidden;
height: 10vh;
width: 100%;
z-index: 11;
/*outline: 0.1vw dashed orange;*/
}
.vertical-center-contrast {
position: absolute;
top: 73.5vh; /*top: 82vh;*/
padding-top: 10px;
margin: 0;
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}
.contrast {
position: relative;
font-family: "Vazir";
direction: rtl;
text-shadow: 1px 1px 2px rgba(0, 0, 0, 1);
text-align: center;
width: 100%;
font-size: 2vw;
color: rgb(248, 247, 250);
opacity: 0;
margin: 0 auto;
}
.contrastShow {
animation: contrastAnimeShow 0.3s ease-in-out;
animation-fill-mode: forwards ;
}
.contrastHide {
animation: contrastAnimeHide 0.3s ease-in-out;
animation-fill-mode: forwards ;
}
#-webkit-keyframes contrastAnimeShow {
0% { opacity: 0; top: 4vh }
100% { opacity: 1; top: 1.2vh }
}
#-webkit-keyframes contrastAnimeHide {
0% { opacity: 1; top: 1.2vh }
100% { opacity: 0; top: 4vh }
}
.zoomIn {
-webkit-animation: heartbeat 1.5s ease-in-out infinite both;
animation: heartbeat 1.5s ease-in-out infinite both;
}
#-webkit-keyframes heartbeat {
from {
-webkit-transform: scale(1);
transform: scale(1);
-webkit-transform-origin: center center;
transform-origin: center center;
-webkit-animation-timing-function: ease-out;
animation-timing-function: ease-out;
}
to {
-webkit-transform: scale(2);
transform: scale(2);
-webkit-animation-timing-function: ease-out;
animation-timing-function: ease-out;
}
}
<div class ="vertical-center-contrast contrast-container">
<p id="contrast" class="contrast"></p>
</div>
Then I want to animate the text by adding a new class attached to a keyframe animation (using a setTimeout at the very end f the code).
But unexpectedly the text just hides and there is no animation ?!
What I missed and how to fix this?

The heartbeat animation is running, your element is just hidden via opacity. You should set the initial value of .contrast opacity to 1 and use the backwards fill-mode. This way it doesn't fallback to 0 if you overwrite the animation.
const contrast = document.getElementById("contrast");
function contrastHide() {
//sfxPlay(sfx.caption_hide);
contrast.classList.add("contrastHide");
contrast.classList.remove("contrastShow");
}
function contrastShow(text) {
contrast.innerHTML = text;
contrast.classList.add("contrastShow");
contrast.classList.remove("contrastHide");
}
contrastShow("This is the text");
setTimeout(() => {
contrast.classList.add("zoomIn");
}, 3000);
.contrast-container {
overflow: hidden;
height: 10vh;
width: 100%;
z-index: 11;
/*outline: 0.1vw dashed orange;*/
}
.vertical-center-contrast {
position: absolute;
top: 73.5vh; /*top: 82vh;*/
padding-top: 10px;
margin: 0;
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}
.contrast {
position: relative;
font-family: "Vazir";
direction: rtl;
text-shadow: 1px 1px 2px rgba(0, 0, 0, 1);
text-align: center;
width: 100%;
font-size: 2vw;
color: rgb(248, 247, 250);
opacity: 1;
top: 1.2vh;
margin: 0 auto;
}
.contrastShow {
animation: contrastAnimeShow 0.3s ease-in-out;
animation-fill-mode: backwards ;
}
.contrastHide {
animation: contrastAnimeHide 0.3s ease-in-out;
animation-fill-mode: backwards ;
}
#-webkit-keyframes contrastAnimeShow {
0% { opacity: 0; top: 4vh }
100% { opacity: 1; top: 1.2vh }
}
#-webkit-keyframes contrastAnimeHide {
0% { opacity: 1; top: 1.2vh }
100% { opacity: 0; top: 4vh }
}
.zoomIn {

Restart CSS3 animation using Javascript

I'm creating a CSS3/HTML5 banner ad and want to loop the animations over once they're all complete. I know there's a method to check with Javascript to check if a particular animation has ended, however I cannot figure out how to then restart the animations from all of their start points.
Essentially I have 3 'frames' with different information, each one will fade in and then fade back out, to be replaced with the next frame - once the last frame has faded back out, I want the animations to start over again. Doing this solely with CSS3 is way too tricky, because the timings of the animations and points in which the opacity is set to 0 have to be different for each animation.
As you can see from the JSFiddle, it plays once, then stops which is great, now I just need to re-trigger the animation once click_through2 finishes executing the animation.

You could check for the end of the animation by responding to the endanimation event (of which there are several browser-dependent variants), reloading the relevant nodes, and repeating the whole process. Note I applied a factor 10 to the speed of the animations so you can see the effect faster:
// Define a function that listens to all prefix variants of endanimation events:
function whenAnimationEnd(element, callback) {
element.addEventListener('animationend', callback, false);
element.addEventListener('webkitAnimationEnd', callback, false);
element.addEventListener('oanimationend', callback, false);
element.addEventListener('MSAnimationEnd', callback, false);
}
(function repeat() {
whenAnimationEnd(document.querySelector('.click_through2'), function(e) {
var container = document.querySelector('.ad_container');
var dupe = container.cloneNode(true);
container.parentNode.replaceChild(dupe, container);
repeat();
});
}());

Use a setTimeout and try setting the animation property to something else and then set it to the classname again so that it restarts the animation.
Something like:
setTimeout(function(){
document.querySelector('.someclass').classList.remove("run-animation").classList.add("run-animation");
}, 1000)

Remove the class to which the animation is assigned to and add it again (maybe with timeout) and the animation starts again.

Safari not always firing animationend with chained animation

I dont know what im doin wrong here.
My animation worked fine till last days. After debugging ive seen the animationend event is not getting fired on my last two animations in the chain.

Chrome is working fine. Safari (9.1.2) doesnt work!
Another funny issue ive found: With alt+tab out and back in the animation will get called to end aslong there is no iframe usage. So you cant see in the fiddle demo.

Image Display on Hover

Code is for displaying an image during a hover.
In addition to not getting the images to display while hovering, I am getting a white border on the top (about 17px) and right side of the image.
Any suggestions as to why this is happening?

Your jsFiddle was messed up, that's all. You shouldn't put the <style></style> tags in the CSS area, and you shouldn't put the <script></script> tags in the JavaScript area. Also, to include jQuery, you need to include it as an external resource, which is a section in the left sidebar. You put your resource URL in the text box, and click the plus button at its right. Here's a fixed version, with your HTML cleaned up too.

I'm guessing you're new to jsfiddle? I've formatted it correctly now, is that working?
$('.nav li a').hover(function() {
$('.img-place').toggleClass($(this).data('target'));
});
$('.nav-wrap .img-place, .nav-wrap').height($(window).height());

Seamlessly transition back and forth with only one animation class?

I want to use one class to trigger an animation, and upon removal of that class redo that animation in reverse.
It's hard to visualize, so I've created a CodePen of where I'm at currently.
You'll notice that when .zoom is removed from #box, the #box just vanishes. It doesn't do the animation in reverse, which is ultimately the goal.
How can I seamlessly transition back and forth, with only one animation class? Normally I might use transitions, but you can't transition with transforms.

Try adding .zoomout class , css animations , utilizing .removeClass() , second class at .toggleClass()
window.onclick = function() {
if (!$("#box").is(".zoom")) {
$("#box").removeClass("zoomout")
.toggleClass("zoom");
} else {
$("#box").toggleClass("zoom zoomout");
}
};
