jQuery Card Flip on Mouseenter/Mouseexit - triggering multiple times

The issue is that if you do the mouseenter and wiggle your mouse around fast, it will trigger the flipping action multiple times, making it flicker or look strange. Is there a better way to do what I'm doing here?
jQuery('.card').mouseenter(function(e) {
e.stopPropagation();
jQuery(this).addClass('flipped');
}).mouseleave(function(e) {
e.stopPropagation();
jQuery(this).removeClass('flipped');
});

The issue is that if you do the mouseenter and wiggle your mouse around fast, it will trigger the flipping action multiple times, making it flicker or look strange. Is there a better way to do what I'm doing here?

One way to solve the issue is to add a wrapper around the card and listen to events on the wrapper instead of the card
jQuery('.wrapper').mouseenter(function(e) {
e.stopPropagation();
let $this = jQuery(this).find('.card');
if(!$this.hasClass('flipped')){
$this.addClass('flipped');
}
}).mouseleave(function(e){
e.stopPropagation();
jQuery(this).find('.card').removeClass('flipped');
});
.wrapper{
width: 150px;
height: 300px;
}
.card {
width: 100%;

CSS card flip animation

I am trying to build an animation where each time a card is clicked the card flips over and reveals the opposite side. The words on each side of the card will change every time the card is flipped. The problem I am having is that the front face of my card only is visible on sporadic occasions. I cannot find any logic to why the front face is normally not visible but occasionally will be visible.
This is my jsfiddle: https://jsfiddle.net/tdammon/ucf6mx1q/
Here is the HTML structure:
<body>
<section>
<div id="headerSection">
<h1>Heard At Prime</h1>
</div>
<div id='whiteBlock'>
<div id='front'>hey</div>
<div id='back'>hi</div>
</div>
</section>
</body>
</html>
Here is the flipping logic for the #whiteBlock div:
$(document).ready(onReady);
function onReady(){
$('#whiteBlock').on('click', flipIt)
}
quotesArray=['hey','cool saying','funny thing','hahaha'];
function flipIt() {
console.log('flip')
$('#front').empty();
$('#back').empty();
let firstQuote= quotesArray[Math.floor(Math.random()*quotesArray.length)]
let secondQuote= quotesArray[Math.floor(Math.random()*quotesArray.length)]
$('#front').append(firstQuote);
$('#back').append(secondQuote);
$('#whiteBlock').toggleClass('flip');
};
And the CSS animations:
body {
background-color: blue;
}
section{
perspective: 500px;
}
#whiteBlock{
background-color:white;
height: 100px;
width:100px;
transform: scale(1);
transform-style: preserve-3d;
/* transition: transform .5s; */
display: flex;
justify-content: center;
align-items: center;
/* position: absolute;
animation: move 3s linear infinite; */
}
#whiteBlock:active{
transform:scale(.97);
transition: transform .2s
}
#whiteBlock.flip{
transform:rotateY(180deg)
}
#front{
transform: rotateY(180deg);
backface-visibility: hidden;
}
#back{
position:absolute;
backface-visibility: hidden;
}

backface-visibility still requires vendor prefixes. So you'll need -webkit-backface-visibility for Chrome and Safari and -moz for Firefox.
With a couple changes this more of less works for me in Safari and should be a good starting point:
$(document).ready(onReady);
function onReady() {
$('#whiteBlock').on('click', flipIt)
}
let quotesArray = ['hey', 'cool saying', 'funny thing', 'hahaha'];
function flipIt() {
console.log('flip')
$('#front').empty();
$('#back').empty();
let firstQuote = quotesArray[Math.floor(Math.random() * quotesArray.length)]
let secondQuote = quotesArray[Math.floor(Math.random() * quotesArray.length)]
$('#front').append(firstQuote);
$('#back').append(secondQuote);
$('#whiteBlock').toggleClass('flip');
};
section {
perspective: 500px;
}
#whiteBlock {
border: 1px solid #333;
height: 100px;
width: 100px;
transition: 0.6s;
transform-style: preserve-3d;
-webkit-transform-style: preserve-3d;
-moz-transform-style: preserve-3d;
position: relative;
}
#whiteBlock.flip {
transform: rotateY(180deg)
}
#front {
transform: rotateY(0deg);
backface-visibility: hidden;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
}
#back {
transform: rotateY(180deg);
backface-visibility: hidden;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<section>
<div id="headerSection">
<h1>Heard At Prime</h1>
</div>
<div id='whiteBlock'>
<div id='front'>hey</div>
<div id='back'>hi</div>
</div>

backface visibility not working in safari

I am trying to uss cssflip animation in my code in which the element rotates when hovered upon. I have used transition and backface-visibilty property. It is working fine on chrome but it is not working properly on safari. I have used webkit prefix as well for safari browser.
`.card-container{
margin-top: 9%;
perspective: 900px;
-webkit-perspective: 900px;
z-index: 1;
}
.card{
float: left;
width: 78.5%;
height: 35%;
margin-top: 25%;
border: 1px solid #A08C87;
transition: all 0.6s ease;
-webkit-transition: all 0.6s ease;
transform-style: preserve-3d;
-webkit-transform-style: preserve-3d;
}
#front #back{
color: white;
backface-visibility: hidden;
-webkit-backface-visibility: hidden;
}
front{
backface-visibility: hidden;
-webkit-backface-visibility: hidden;
}
back{
display: flex;
backface-visibility: hidden;
-webkit-backface-visibility: hidden;
font-size: 20px;
}
.card-container:hover .card{
transform: rotateY(180deg);
-webkit-transform: rotateY(180deg);
}
back{
transform: rotateY(180deg);
-webkit-transform: rotateY(180deg);
}`

I think the issue here is with the
backface-visibility: hidden;
It's not being supported in ios and in safari.
In your code just replace the code with
#front #back {
color: white;
-webkit-perspective: 0;
-webkit-backface-visibility: hidden;
-webkit-transform: translate3d(0,0,0);
visibility:visible;
backface-visibility: hidden;
}
I hope this will help you.

How do I automatically have Javascript-animations (with CSS) open in a certain order?

I'm trying to create an animated envelope on my site.
Right now, the code I'm trying to use only starts the next step of the animation on click.
My question would be how I get the animations to occur automatically after a certain amount of time.
This is how the code looks right now:
Javascript:
<script type="text/javascript">
// Wait for page to load
window.onload=function(){
$(document).ready(function () {
// Hide the div
$("#card").hide();
// Show the div after 5s
$("#card").delay(5000).fadeIn(100);
});
// Add Flip Envelope Event Handler
document.getElementById('envelope_front').onclick = function(){
document.getElementById('envelope_front').classList.toggle('flipped');
document.getElementById('envelope_back').classList.toggle('flipped');
}
// Add Open Envelope Event Handler
document.getElementById('flap_outside').onclick = function(){
document.getElementById('flap_outside').classList.toggle('open');
document.getElementById('flap_inside').classList.toggle('open');
// Add Remove Card Event Handler
// This is added after "Open Envelope" so that card can't be removed
// until the envelope has been opened
document.getElementById('envelope_back_outside').onclick = function(){
document.getElementById('card').classList.toggle('removed');
return false;
}
return false;
}
// Open Card
document.getElementById('card').onclick = function(){
document.getElementById('card_outside_front').classList.toggle('open');
document.getElementById('card_inside_top').classList.toggle('open');
return false;
}
}
</script>

You can use setTimeout with a given x delay time:
setTimeout(function() {
//put your animation code here
}, 2000);

To delay the animations in JS (and JQuery) you can use the delay function, you already are using it in some places. If you want the delay on the CSS you should apply the animation-delay property

You can use a timeout or you can use css animation-delay property without using too much javascript (I usually pick the second).

Adding preventDefault() and stopPropagation()

I am new in coding in general, most especially javascript.
I made a flip div effect. But I noticed that when clicking one .button to trigger the flip effect, all the other divs that are similar in a page are also triggered. So I am trying to add both .preventDefault() and .stopPropagation() when flipping a div, so far its a big FAIL
As a starter, I came up with this code..
$('.insidecontent .button').click(function () {
$('.insidecontent').addClass('flipped');
$('.insidecontent').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$('.insidecontent').removeClass('flipped');
$('.insidecontent').addClass('unflipped');
});
Demo here: http://jsfiddle.net/uriri/ke7kqvvk/3/
A friend of mine suggested that I should use .parents() on the current target inside the .click() function. But after reading the jQuery documentation, I am totally lost!

You don't need to stop click event or prevent default. You just need to flip right element. Right not you are adding/removing classes to/from all .insidecontent, while you need to select only parent element of the clicked button:
$('.insidecontent .button').click(function () {
$(this).closest('.insidecontent').addClass('flipped').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$(this).closest('.insidecontent').removeClass('flipped').addClass('unflipped');
});
Demo: http://jsfiddle.net/ke7kqvvk/5/
Or shorter optimized version can be:
$('.insidecontent').find('.button, .button-c').click(function () {
$(this).closest('.insidecontent').toggleClass('flipped unflipped');
});
Demo: http://jsfiddle.net/ke7kqvvk/6/

preventDefault() and stopPropagation() won't help here. You need to use a selector that's more specific than all the elements with the same class.
$('.insidecontent .button').click(function () {
$(this).closest('.insidecontent').addClass('flipped').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$(this).closest('.insidecontent').removeClass('flipped').addClass('unflipped');
});

Have you learned about the "this" keyword yet? In a JQuery click handler, $(this) refers to the element that the handler is called on. So, if you put removeClass and addClass methods on $(this) it will only affect that one element. You can traverse using this too... so your code would look like this:
$('.insidecontent .button').click(function () {
$(this).parent().find('.insidecontent').addClass('flipped');
$(this).parent().find('.insidecontent').removeClass('unflipped');
});
$('.insidecontent .button-c').click(function () {
$(this).parent().find('.insidecontent').removeClass('flipped');
$(this).parent().find('.insidecontent').addClass('unflipped');
