Getting Top/Right values ​from a css-animated element

I'm trying to get the Top and Right values from an element being rotated by a CSS animation, for this I am using the following code:
HTML:
<div id="ball1"> </div>
CSS:
#keyframes spin {
0% {transform: rotate(0deg);}
100% {transform: rotate(360deg);}
}
#ball1 {
transform-origin: center right;
animation: spin 2.5s linear 0s infinite forwards;
position: relative;
background-color: #7883f7;
width: 10;
height: 10;
border-radius: 10px;
}
Javascript:
console.log(window.getComputedStyle(document.getElementById("ball1"), null).top);
console.log(window.getComputedStyle(document.getElementById("ball1"), null).right);
However it returns a value of 0px, I wanted to get the value from Right and Top as if I was manually setting them (and not by the transform animation).
If this is not possible, is there a way to simulate a "circle" rotation and return the right/top values without using the transform?
ie:

Use getBoundingClientRect():
const ball = document.getElementById("ball");
setInterval(() => {
const rect = ball.getBoundingClientRect();
console.log(rect.top, rect.right);
}, 300);
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
#ball {
transform-origin: center right;
animation: spin 2.5s linear 0s infinite forwards;
position: relative;
background-color: #7883f7;
width: 10px;
height: 10px;
border-radius: 10px;
}
<div id="ball"></div>

Here is an approximation using top/left. The trick is to animate each property individually alternating the ease function to simulate the circular path:
.box {
width:100px;
height:100px;
position:relative;
}
#ball1 {
animation:
Atop 2.5s infinite,
Aleft 2.5s infinite;
position: absolute;
background-color: #7883f7;
width: 10px;
height: 10px;
border-radius: 10px;
}
#keyframes Atop {
0%,50%,100% {
top:50%;
animation-timing-function: ease-out;
}
25% {
top:0%;
animation-timing-function: ease-in;
}
75% {
top:100%;
animation-timing-function: ease-in;
}
}
#keyframes Aleft {
0%,100% {
left:0;
animation-timing-function: ease-in;
}
25%,75% {
left:50%;
animation-timing-function: ease-out;
}
50% {
left:100%;
animation-timing-function: ease-in;
}
}
<div class="box">
<div id="ball1"> </div>
</div>

Detect css animation stop

I have a spaceship object in my website that moves to left to right(end to the view port) in the screen.
I need to show another spaceship object moves right to left once that above mentioned spaceship object reach to end(screen view port).
The problem
I tried to give second spaceship object "animation delay" but it's not working as I wanted. Because browser width different from screen to screen.
Here is my code.
.spaceship-1 img {
width: 100px;
animation: spaceship-1 10s ease-in-out 1;
animation-fill-mode: forwards;
}
#-webkit-keyframes spaceship-1 {
0% {
transform: translateX(0);
}
100% {
transform: translateX(100vw);
}
}
.spaceship-2 img {
width: 100px;
animation: spaceship-2 10s ease-in-out 1;
animation-fill-mode: forwards;
animation-delay: 5s;
position: absolute;
right: 0;
bottom: 15px;
}
#-webkit-keyframes spaceship-2 {
0% {
transform: translateX(0);
}
100% {
transform: translateX(-100vw);
}
}
<div class="spaceship-1">
<img src="http://i63.tinypic.com/24nguhx.png" alt="">
</div>
<div class="spaceship-2">
<img src="http://i68.tinypic.com/2lsxjpx.png" alt="">
</div>
Here is the Jsfiddle Any ideas?

If you want the second animation to start right after the first one, you have to set an animation-delay equal to the animation-duration of the first one, witch is 10s.
And also you should make both of them absolute.
body{
background:#f6f6f6;
overflow-x:hidden;
}
.spaceship-1 img{
width:100px;
animation: spaceship-1 10s ease-in-out 1 ;
animation-fill-mode: forwards;
position:absolute;
left: 0;
top: 10px;
}
#-webkit-keyframes spaceship-1 {
0% {
transform: translateX(0);
}
100% {
transform: translateX(calc(100vw - 100px)) ;
}
}
.spaceship-2 img{
width:100px;
animation: spaceship-2 10s ease-in-out 1 ;
animation-fill-mode: forwards;
animation-delay:10s;
position:absolute;
transform: rotate(180deg);
right: 0;
bottom: 10px;
}
#-webkit-keyframes spaceship-2 {
0% {
transform: translateX(0) rotate(180deg);
}
100% {
transform: translateX(calc(-100vw + 100px)) rotate(180deg);
}
}
<div class="spaceship-1">
<img src="http://i63.tinypic.com/24nguhx.png" alt="">
</div>
<div class="spaceship-2">
<img src="http://i63.tinypic.com/24nguhx.png" alt="">

How to apply a hover effect on an element which has already been handled by an forward animation?

I have a text and block in an animation of an SVG element.
Here in my example i simplified everything.
I want to have one initial animation and afterwards a hover animation on the block element. The initial animation is fine as it is. (use chrome to have equals measurements). But after the initial animation the user should be able to hover the block and the block itself should resize (which is also working already) and the text should get an opacity of 1. But this won't work since the opacity is already set by the keyframe animation.
Any suggestions on how to work around on this one?
I don't mind if i use JS or CSS or any frameworks. I don't rely on CSS animations. Just used them because i thought i'd be cleaner.
Important Edit: I forgot a simple but very important thing. Before the animation there are some other animations on different elements. So i have a delay of let's say 2 seconds. Before the animation starts, the opacity should be 0 so the text is not visible until the animation starts. Sorry, forgot about that!
.text{
font-weight: bold;
opacity: 0;
transition: all .8s;
animation: showText 3s ease-in-out forwards;
animation-delay: 2s;
}
.text:hover{
opacity: 1;
transition: all .8s;
}
.block{
top: 50px;
left: 50px;
position: absolute;
height: 20px;
width: 20px;
background-color: red;
transition: all .8s;
animation: popup 3s ease-in-out;
animation-delay: 2s;
}
.block:hover{
transform: scale(2);
transition: all .8s;
}
#keyframes showText {
0% {
opacity: 0;
}
50% {
opacity: 1;
}
100% {
opacity: 0.3;
}
}
#keyframes popup {
0% {
transform: scale(1);
}
50% {
transform: scale(2);
}
100% {
transform: scale(1);
}
}
<div class='text'>
Foo Bar!
</div>
<div class='block'>
</div>

Instead of a forwards animation, you can simply set the initial opacity to 0.3.
EDIT:
I'm fairly confident that forwards animation styles can't be easily overridden (though I'm unable to find it in documentation for some reason), so you could do similarly to what was originally suggested and just extend the time of the animation like so:
.text{
font-weight: bold;
/* Start out at 0.3 */
opacity: 0.3;
transition: all .8s;
/* 2s + 3s = 5s */
animation: showText 5s ease-in-out; /* no forwards */
}
.text:hover{
opacity: 1;
transition: all .8s;
}
.block{
top: 50px;
left: 50px;
position: absolute;
height: 20px;
width: 20px;
background-color: red;
transition: all .8s;
animation: popup 3s ease-in-out;
}
.block:hover{
transform: scale(2);
transition: all .8s;
}
#keyframes showText {
0% {
opacity: 0;
}
50% {
opacity: 0;
}
/* Note the new animation keyframe locations */
70% {
opacity: 1;
}
100% {
opacity: 0.3;
}
}
#keyframes popup {
0% {
transform: scale(1);
}
50% {
transform: scale(2);
}
100% {
transform: scale(1);
}
}
<div class='text'>
Foo Bar!
</div>
<div class='block'>
</div>

First, you need to remove forwards from the .text animation. You can use Javascript's mouseenter and mouseleave events to set the text's opacity when .block is hovered over.
.text{
font-weight: bold;
opacity: 0;
transition: all .8s;
animation: showText 3s ease-in-out;
animation-delay: 2s;
}
.text:hover{
opacity: 1;
transition: all .8s;
}
.block{
top: 50px;
left: 50px;
position: absolute;
height: 20px;
width: 20px;
background-color: red;
transition: all .8s;
animation: popup 3s ease-in-out;
animation-delay: 2s;
}
.block:hover{
transform: scale(2);
transition: all .8s;
}
#keyframes showText {
0% {
opacity: 0;
}
50% {
opacity: 1;
}
100% {
opacity: 0.3;
}
}
#keyframes popup {
0% {
transform: scale(1);
}
50% {
transform: scale(2);
}
100% {
transform: scale(1);
}
}
<div class='text' id="text" onmouseenter="function1()" onmouseleave="function2()">
Foo Bar!
</div>
<div class='block' onmouseenter="function1()" onmouseleave="function2()">
</div>
<script>
setTimeout(function(){
document.getElementById("text").style.opacity = "0.3";
}, 3000)
function function1(){
document.getElementById("text").style.opacity = "1";
}
function function2(){
document.getElementById("text").style.opacity = "0.3";
}
</script>

Animation for carousel with ng-boostrap and Angular 2

I am using the carousel component with ng-bootstrap. I understand there's an open issue for a proper animation feature that works correctly with the angular 2 component life cycle right now (Github issue).
My question: is there a way to use CSS as a workaround for the animation?
I have put up a plunker that has fade in effect for the carousel, but not fade out.
.carousel-item.active{
-webkit-animation: fadein 1.4s;
-moz-animation: fadein 1.4s;
-ms-animation: fadein 1.4s;
-o-animation: fadein 1.4s;
animation: fadein 1.4s;
}
#keyframes fadein {
from { opacity: 0; }
to { opacity: 1; }
}
/* Firefox < 16 */
#-moz-keyframes fadein {
from { opacity: 0; }
to { opacity: 1; }
}
/* Safari, Chrome and Opera > 12.1 */
#-webkit-keyframes fadein {
from { opacity: 0; }
to { opacity: 1; }
}
/* Internet Explorer */
#-ms-keyframes fadein {
from { opacity: 0; }
to { opacity: 1; }
}
/* Opera < 12.1 */
#-o-keyframes fadein {
from { opacity: 0; }
to { opacity: 1; }
}
Is there a way to make a fade out work? I have tried transition but failed.

I wanted a fade in/fade out the transition between slides and found a simpler solution to this:
::ng-deep {
.carousel-item {
transition: opacity 0.7s ease !important;
position: absolute !important;
display: block !important;
opacity: 0;
}
.carousel-item.active {
position: relative !important;
opacity: 1;
}
}
If you don't want to use ::ng-deep (it seems that is going to be deprecated, or at least I read so last week in angular.io) you can use a global styles file that will reach all classes in all components

Alright, answering my own question. The following CSS hack will make the animation work just fine
ngb-carousel {
width: inherit;
height: inherit;
}
.carousel-inner {
overflow: visible;
}
.carousel-item {
display: flex !important;
opacity: 0;
visibility: hidden;
transition: opacity 1.2s ease-in-out, visibility 1.2s;
z-index: -1;
position: absolute;
}
.carousel-item.active{
opacity: 1;
visibility: visible;
z-index: 10;
}
.carousel-control-prev {
z-index: 20;
}
.carousel-control-next {
z-index: 20;
}
.carousel-indicators{
z-index: 20;
}
Working Plunker

I managed to create left-to-right slide animation based on your approach. active slide goes out with transition to the right when it loses .active and then new .active slides in with delayed animation.
though I recommend using ngx-swiper-wrapper instead - best angular carousel I found so far (https://idangero.us/swiper/)
.carousel-inner {
width: 640px;
height: 240px;
}
.carousel-item {
padding: 40px 55px;
opacity: 0;
transition: opacity .3s ease-in-out;
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
z-index: 0;
display: block !important;
}
.carousel-item.active {
z-index: 1;
opacity: 1;
transition-delay: .3s;
transform: none;
animation: slideFromLeft .3s;
animation-delay: .3s;
}
#keyframes slideFromLeft {
from {
transform: translateX(-100%);
}
to {
transform: none;
}
}

Here are two animations I used in Angular 9, ng-bootstrap version 6.0.0. Easiest way is to give an entrance animation to .carousel-item.active. Animations are taken from animista.net/play/entrances. Just make sure you add the css to global styles.css
Animation 1
.carousel-item.active {
-webkit-animation: flip-in-ver-left 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
animation: flip-in-ver-left 0.5s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
}
#-webkit-keyframes flip-in-ver-left {
0% {
-webkit-transform: rotateY(80deg);
transform: rotateY(80deg);
opacity: 0;
}
100% {
-webkit-transform: rotateY(0);
transform: rotateY(0);
opacity: 1;
}
}
#keyframes flip-in-ver-left {
0% {
-webkit-transform: rotateY(80deg);
transform: rotateY(80deg);
opacity: 0;
}
100% {
-webkit-transform: rotateY(0);
transform: rotateY(0);
opacity: 1;
}
}
Animation 2
.carousel-item.active {
-webkit-animation: tilt-in-fwd-tr 0.6s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
animation: tilt-in-fwd-tr 0.6s cubic-bezier(0.250, 0.460, 0.450, 0.940) both;
}
#-webkit-keyframes tilt-in-fwd-tr {
0% {
-webkit-transform: rotateY(20deg) rotateX(35deg) translate(300px, -300px) skew(-35deg, 10deg);
transform: rotateY(20deg) rotateX(35deg) translate(300px, -300px) skew(-35deg, 10deg);
opacity: 0;
}
100% {
-webkit-transform: rotateY(0) rotateX(0deg) translate(0, 0) skew(0deg, 0deg);
transform: rotateY(0) rotateX(0deg) translate(0, 0) skew(0deg, 0deg);
opacity: 1;
}
}
#keyframes tilt-in-fwd-tr {
0% {
-webkit-transform: rotateY(20deg) rotateX(35deg) translate(300px, -300px) skew(-35deg, 10deg);
transform: rotateY(20deg) rotateX(35deg) translate(300px, -300px) skew(-35deg, 10deg);
opacity: 0;
}
100% {
-webkit-transform: rotateY(0) rotateX(0deg) translate(0, 0) skew(0deg, 0deg);
transform: rotateY(0) rotateX(0deg) translate(0, 0) skew(0deg, 0deg);
opacity: 1;
}
}

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");
}
};
#box {
width: 256px;
height: 256px;
background: black;
opacity: 0;
display: block;
transform: scale(1.15, 1.15);

-webkit-animation-fill-mode: both;
}
.zoomout {
animation: zoomout 500ms;
animation-fill-mode: both;
-moz-animation: zoomout 500ms;
-moz-animation-fill-mode: both;
-webkit-animation: zoomout 500ms;
