Spining icon not rotating in the iOS version 15.3 + but working fine in lower 15.3 version

spining icon not spinning in the iOS version > 15.3 or 16.1 but it is working fine in the lower < 15 iOS version iphone and ipad and Android, browser.
Please find the below css code for reference. i have tried with webkit for safari and also tried with transform: rotate(-360deg). but spinner is not spinning/rotating in the iOS device alone. please help me for fixing this issue.
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
#-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
}

keyframes creating issue when using with jQuery

I am trying to create bubble and also bubble burst on click.I am using two keyframes, One for bubbling, and other is when click on bubble.
Problem is when I click on bubble the effect is showing on wrong areas. Here is my code sample. i can't understand where is the issue is
because of two keyframes timing is wrong. how to adjust click effect where the bubble is exactly click.
$('.bubbles li').on('click',mouseremove, function () {
const thisBubble = $(this);
thisBubble.addClass('bubble-pop');
setTimeout(() => {
thisBubble.hide();
mouseremove(thisBubble);
}, 500);
});
function mouseremove(thisBubble) {
thisBubble.removeClass('bubble-pop');
setTimeout(() => {
thisBubble.show();
}, 500);

Multiple animation rotate in css at once call in toggle onclick of one element (slow rotate, medium rotate, fast rotate)?

I have 3 animations on css what I've made in fiddle that are "animate1 (as a slow rotate), animate2 (as a medium rotate) and animate3 (as a fastest rotate) which is want to running by toggle onClick on an Element of "<h1>". untiil now of my achievements is just only till running to animate2 only after that I don't know how ? Please to anyone for solve this case and sorry for my bad english ...
demo on fiddle
function Animation() {
var anim = document.getElementsByTagName("h1")[0];
anim.innerText = "|"; anim.className = "animate1";
anim.addEventListener("webkitAnimationEnd", function() {anim.className = 'animate2'});
anim.addEventListener("animationend", function() {anim.className = 'animate2'});
}

Use only one animation and simply increase/decrease the duration to control the speed:
var i = 7;
var anim = document.getElementsByTagName("h1")[0];
function Animation() {
anim.className = "animate";
anim.style.animationDuration = (i-=2) + 's';
if(i<=0) {
i=7;
}
}
#keyframes twister {
from {
transform: rotate(0);
}
to {
transform: rotate(360deg);
}
}
.animate {
animation: twister 5s infinite linear;
}
.center {
font-family: 'Montserrat', sans-serif;
transform: translateY(-50%);
text-align: center;
position: fixed;
margin: 0px;
width: 100%;
color: #222;
z-index: 1;
top: 50%;
}
<div class="center">

How move divs up/down using CSS animation without a "blink" between directions?

I'm trying to move these divs up and down based on clicks:
Initial click moves them up
Next Click moves them down (then repeat on next clicks)
Moving them up works well, but when i click to move them down, they flash invisible first and then move down. What am I doing wrong?

You achieve your animation by using only transition you don't need to use keyframes
this how css look like :
*
{
margin: 0em;
padding: 0em;
}
html
{
height: 100%;
width: 100%;
}
body
{
height: 100%;
width: 100%;
overflow: hidden;
}
.page
{
position: relative;
height: 100%;
width: 100%;
overflow: hidden;
background-color: red;
transition:all linear 800ms;
}
#page2{
background-color: blue;
}
#page1.leave,#page2.enter
{
transform: translate(0em,-100%);
-webkit-transform: translate(0em,-100%);
-moz-transform: translate(0em,-100%);
}
#page1.enter,#page2.leave
{
transform: translate(0em,-0%);
-webkit-transform: translate(0em,-0%);
-moz-transform: translate(0em,-0%);
}

Looking to achieve rectangle radial wipe animation reveal

I'm working on a full-width hero animation that would reveal an image/HTML div in a radial wipe manner. Here's what I have thus far: http://jsfiddle.net/andrewkerr/bjqSv/ - (code below) which is largely based these pieces:http://codepen.io/tmyg/pen/bwLom and http://css-tricks.com/css-pie-timer/ - The issue I'm running into is the fact that the image tiles because the animation splits the "pie" in half - I'm looking to perform the effect without having the image tile. I'm not opposed to a Javascript solution. Thanks.
//html
<div class="spinner-new">
<span><em></em></span>
<span><em></em></span>
</div>
//css
.spinner-new {
width: 100%;
height: 400px;
margin: 0 auto;
position: relative;
background:#3f9e35;
overflow:hidden
}
.spinner-new span em {
background-image:url('http://cdn.acidcow.com/pics/20100707/funny_family_photos_04.jpg');
-webkit-animation-delay:1s;
-webkit-animation-duration: 3s;
}
#-webkit-keyframes rotate-rt {
0% { -webkit-transform: rotate(0deg); }
25% { -webkit-transform: rotate(180deg); }
50% { -webkit-transform: rotate(180deg); }
75% { -webkit-transform: rotate(180deg); }
100% { -webkit-transform: rotate(180deg); }
}
#-webkit-keyframes rotate-lt {
0% { -webkit-transform: rotate(0deg); }
25% { -webkit-transform: rotate(0deg); }
50% { -webkit-transform: rotate(180deg); }
75% { -webkit-transform: rotate(180deg); }
100% { -webkit-transform: rotate(180deg); }
}
.spinner-new {
position: relative;
}
.spinner-new span {
width: 50%;
height: 400%;
overflow: hidden;
position: absolute;
}
.spinner-new span:first-child {
left: 0;
}
.spinner-new span:last-child {
left: 50%;
}
.spinner-new span em {
position: absolute;
width: 100%;
height: 100%;
-webkit-animation-iteration-count: 1;
-webkit-animation-timing-function: linear;
animation-fill-mode: forwards;
-webkit-animation-fill-mode: forwards;
}
.spinner-new span:first-child em {
left: 100%;
border-top-left-radius: 0;
border-bottom-left-radius: 0;
-webkit-animation-name: rotate-lt;
-webkit-transform-origin: 0 12.5%;
}
.spinner-new span:last-child em {
left: -100%;
border-top-right-radius: 0;
border-bottom-right-radius: 0;
-webkit-animation-name: rotate-rt;
-webkit-transform-origin: 100% 12.5%;
}

That is my solution.
CSS
#-webkit-keyframes span-left {
0% { right: 0%; }
24.999% { right: 0%;}
25% { right: 50%;}
100% { right: 50%;}
}
#-webkit-keyframes rotate-first {
0% { right: 100%;
-webkit-transform: rotate(0deg);
-webkit-transform-origin: right center; }
24.999% { right: 100%;
-webkit-transform: rotate(180deg);

100% { right: 0%;
-webkit-transform: rotate(360deg);
-webkit-transform-origin: right center; }
}
#-webkit-keyframes rotate-last {
0% { -webkit-transform: rotate(0deg); opacity: 0; }
24.999% { -webkit-transform: rotate(180deg); opacity: 0;}
25% { -webkit-transform: rotate(180deg); opacity: 1;}
50% { -webkit-transform: rotate(360deg); opacity: 1; }
100% { -webkit-transform: rotate(360deg); opacity: 1;}
}
.spinner-new {
width: 400px;
height: 300px;
position: relative;
overflow:hidden;
position: relative;
left: 50px;
top: 20px;
}
.spinner-new span {
width: 50%;
height: 100%;
overflow: hidden;
position: absolute;
}
.spinner-new span:first-child {
right: 50%;
}
.spinner-new span:last-child {
left: 50%;
}
.spinner-new span em {
position: absolute;
width: 100%;
height: 100%;
}
.spinner-new span em,
.spinner-new span:first-child {
-webkit-animation-duration: 30s;
-webkit-animation-iteration-count: infinite;
-webkit-animation-timing-function: linear;
}
.spinner-new span:first-child {
-webkit-animation-name: span-left;
}
.spinner-new span:first-child em {
-webkit-animation-name: rotate-first;
overflow: hidden;
}
.spinner-new span:last-child em {
left: 0;
-webkit-animation-name: rotate-last;
-webkit-transform-origin: left center;
-webkit-transform: rotate(204deg);
}
.spinner-new span em:after {
content: "";
position: absolute;
width: 200%;
height: 100%;
top: 0px;
background-image:url('image.jpg');
background-size: cover;
}
.spinner-new span:first-child em:after {
left: 0px;
}
.spinner-new span:last-child em:after {
right: 0px;
}
The most complex issue is reusing the splitted left element for the right hand beginning.
I have to move the container to the left in the middle of the animation.
The background image is set with cover, and all the size are in percentages, so this solution should be fully responsive
fiddle
The demo has the iteration count to infinite, so it is easier to see it going on.

May not be the most elegant way to accomplish this, but I ended up using CSS animations to reveal pie pieces gradually. Here's a link to the working example: http://jsfiddle.net/andrewkerr/dsTm6/ - code below
