How do start CSS animation on click?
I'm fairly new to front-end dev so please spare me...Anyway, for this codepen project I'm trying to get the animation where a stack of pancakes falls to the plate to activate when you click the button. It should be just an empty plate until the button is clicked.
Not sure why my JS code isn't working but if I target the pancake or stack class, the visuals still remain static.
HTML:
<div class="container">
<div class="plate">
<div class="inner-plate">
</div>
</div>
<button onclick="onclick()">Good Morning!</button>
<div class="stack">
<div class="pancake">
<div class="top-p"></div>
</div>
<div class="pancake p2">
<div class="top-p"></div>
</div>
<div class="pancake p3">
<div class="top-p"></div>
</div>
<div class="pancake p4">
<div class="top-p"></div>
</div>
<div class="pancake p5">
<div class="top-p"></div>
</div>
<div class="pancake p6">
<div class="top-p"></div>
<div class="butter">
<div class = "shadow"></div>
<div class = "top-b"></div>
<div class = "shine"></div>
</div>
</div>
</div>

There are a bunch of things are not right, I've fixed them and marked them with FIX

Use following js (i remove animation from css .pancake class and add transform: translateY(-1000px); to it)
function onClick() {
[...document.querySelectorAll('.pancake')]
.map(x=> x.classList.add('slideIn'));
}
function onClick() {
[...document.querySelectorAll('.pancake')].map(x=> x.classList.add('slideIn'));
}@import url('https://fonts.googleapis.com/css?family=Montserrat:600&display=swap');

You need to add the class identifier . in $(".pancake")

the class identifier is wrong it should be $(".pancake")
$(function() {
$('button').onclick(function() {
$('.pancake').addClass('slideIn');
});
})
javascript
