How to make the css animation responsive?

I want to make this animation responsive and work on any device. I tried using #keyframes but I could not get it to work. On my mobile phone, the animation wouldn't even appear. Any suggestions on how I can make this animation responsive? And make it work on any device?

Removing an element from the CSS file

I want to remove a small button/element that is under my preloader. I am trying to figure out exactly what kind of css file controls that but I am unable to remove that element under the preloader. I thought adding overflow:hidden to the svg would do the trick but it still did not.
This is the code of the preloader:
* {
padding: 0;

I want the container to be aligned vertically centered to the xl-lg-md-sm-col screen resolutions with equal padding or margin from top & bottom.
when ever i try adjusting the padding wave at the bottom also moves along.
Need a output like this https://ibb.co/7x3NF2s

const mn = document.querySelector('#mn');
const sc = document.querySelector('#sc');
setInterval(() => {
let day = new Date();
let hh = day.getHours() * 30;
let mm = day.getMinutes() * deg;
let ss = day.getSeconds() * deg;
hr.style.transform = `rotateZ(${(hh)+(mm/12)}deg)`;
mn.style.transform = `rotateZ(${mm}deg)`;
sc.style.transform = `rotateZ(${ss}deg)`;

Heart Animation on click

So Id like to create an animation where you click on the heart that there is a circle around that heart that's scales up and then fades away. I've tried to give the SVG a border but nothing shows up? I'm honestly not sure what I'm doing wrong here. Any help would be greatly appreciated. I want it to be similar to the Twitter heart but without the dots around the heart when you click it. Here is a link to my codepen https://codepen.io/Brushel/pen/MEEYgQ
(function() {
var animatedHeart, heartanimation, heartanimationthree;
animatedHeart = document.getElementById('heart1');
heartanimation = document.getElementById('heart2');
heartanimationthree = document.getElementById('heart3');
animatedHeart.addEventListener('click', function() {
return animatedHeart.classList.toggle('fill');
});
heartanimation.addEventListener('click', function() {
return heartanimation.classList.toggle('fillup');
});
heartanimationthree.addEventListener('click', function() {
return heartanimationthree.classList.toggle('heartscale');
});
}).call(this);

the last one looks pretty close ! I think there is a simpler (sort of simpler) way to do this in css.
Nicolas Escoffer has a great article about it here:

Code Pen:
https://codepen.io/OxyDesign/pen/avXVbo
otherwise I would suggest creating a keyframes animation that uses the border of the circle div you have created. Be sure to set the circle div outside of the heart .svg so it is not wrapping the element:
I made an example for you below based on your original codepen:
#HTML:
<body>
<div class="container">

creating scroll animation with css

I am trying to create a header menu when I scroll down it to get involved with animation into a circle and when it scrolled up it will be come back again . I checked the window is top if not then animate with javascript . But my code is not working .
$header = $('.header__fake');
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll > 20) {
$header.addClass('animated').removeClass('fix');
} else {
$header.removeClass('animated').addClass('fix');
}
});

I pasted above code in JSfiddle. It works perfectly. See it here
The problem could be with your jQuery lib initialization.
