Css animation in Chrome Extension doesn't work - css

I'm trying to implement this animation: http://materializecss.com/preloader.html#circular
in chrome extension.
The problem is: animation doesn't work for some reason:
.preloader-wrapper.active {
-webkit-animation: container-rotate 1568ms linear infinite;
animation: container-rotate 1568ms linear infinite;
}
Why so?
I've checked everything in Inspect popup - all styles and html structure are replicated exactly as in the materialize.

You have to add the animation keyframes:
#-webkit-keyframes container-rotate {
to {-webkit-transform: rotate(360deg); } }
#keyframes container-rotate {
to {transform: rotate(360deg); } }
Add these lines and it should work.

How to use a subset of animation.css animations?

I want to use https://animate.style/. But it's more than 90 KBs in size.
I just want a very simple bouncing animation. That's all.
Apart from going into the source code and trying to recreate the bouncing keyframes and animations, is there another way to do so?
For example, in Material UI, or in TailwindCSS only what you have used would be included in the final bundle.
Is there something similar for Animate.css too?
If you only need a simple bouncing animation, why not using your own keyframes?
Exemple falling down :
#keyframes myAnim {
0% {
animation-timing-function: ease-in;
opacity: 1;
transform: translateY(-45px);
}
75% {
transform: translateY(10px);
}
100% {
transform: translateY(0px);
}
}
#my_little_square {
width:50px;
height:50px;
background-color:#f00;
animation: myAnim 1s ease 0s 1 normal forwards;
}
<div id="my_little_square">
</div>

(Firefox bug) Font is sloppy when transformed

This question was orginally related to FontAwesome, but is a general firefox problem.
So i'm using the class fa-spin that will spin the icon, here you can find some examples of it.
Here is the spinning css file:
// Spinning Icons
// --------------------------
.#{$fa-css-prefix}-spin {
-webkit-animation: spin 2s infinite linear;
-moz-animation: spin 2s infinite linear;
-moz-animation: spin 2s infinite linear;
-o-animation: spin 2s infinite linear;
animation: spin 2s infinite linear;
}
#-moz-keyframes spin {
0% { -moz-transform: rotate(0deg); }
100% { -moz-transform: rotate(359deg); }
}
#-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(359deg); }
}
#-o-keyframes spin {
0% { -o-transform: rotate(0deg); }
100% { -o-transform: rotate(359deg); }
}
#-ms-keyframes spin {
0% { -ms-transform: rotate(0deg); }
100% { -ms-transform: rotate(359deg); }
}
#keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(359deg); }
}
Now all works fine in chrome and IE10, however it doesn't in firefox :
jsFiddle.
When you run it for the first time it looks just good, but try the interact with the site(for example: scroll or run the script again in jsFiddle). The animation becomes all jittery. I have no idea what could cause this strange behavior, hope that anyone could help me.
Edit
The problem occurs on Windows 7 32-bit and 25.0 version of Firefox(No add-ons).
However it does work at my home PC, where it also has Windows 7 32-bit 25.0 firefox.
An preview how it looks on my screen:
Note that it works for the first couple of seconds but after it will get jittery (this stuttering is because my .gif is bad).
See my answer for more information
Before you want to add this 'hack', you should first try to update your driver
What i did notice is that IE and Chrome actually makes the text blurry, which FF doesn't. I thought of using the blur filter, but that didn't work. Also the font width didn't stayed the same, so i needed something that or reminded the client of his width or force the width to be static at all time.
I came across the SVG filter XML url, that was special for Firefox 10+ and Firefox on android. I tryed to apply this to my element and my problem was completly gone!
i did use <feColorMatrix type=saturate values=1/> so the saturate filter didn't take away the colors.
filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'saturate\' values=\'1\'/></filter></svg>#grayscale");
When adding this to the .fa-spin class that FontAwesome uses, it'll work on every spinning element.

How to reverse an animation on mouse out after hover

So, it is possible to have reverse animation on mouse out such as:
.class{
transform: rotate(0deg);
}
.class:hover{
transform: rotate(360deg);
}
but, when using #keyframes animation, I couldn't get it to work, e.g:
.class{
animation-name: out;
animation-duration:2s;
}
.class:hover{
animation-name: in;
animation-duration:5s;
animation-iteration-count:infinite;
}
#keyframe in{
to {transform: rotate(360deg);}
}
#keyframe out{
to {transform: rotate(0deg);}
}
What is the optimal solution, knowing that I'd need iterations and animation itself?
http://jsfiddle.net/khalednabil/eWzBm/
I think that if you have a to, you must use a from.
I would think of something like :
#keyframe in {
from: transform: rotate(0deg);
to: transform: rotate(360deg);
}
#keyframe out {
from: transform: rotate(360deg);
to: transform: rotate(0deg);
}
Of course must have checked it already, but I found strange that you only use the transform property since CSS3 is not fully implemented everywhere. Maybe it would work better with the following considerations :
Chrome uses #-webkit-keyframes, no particuliar version needed
Safari uses #-webkit-keyframes since version 5+
Firefox uses #keyframes since version 16 (v5-15 used #-moz-keyframes)
Opera uses #-webkit-keyframes version 15-22 (only v12 used #-o-keyframes)
Internet Explorer uses #keyframes since version 10+
EDIT :
I came up with that fiddle :
http://jsfiddle.net/JjHNG/35/
Using minimal code. Is it approaching what you were expecting ?
Its much easier than all this: Simply transition the same property on your element
.earth { width: 0.92%; transition: width 1s; }
.earth:hover { width: 50%; transition: width 1s; }

I don't think this is achievable using only CSS animations. I am assuming that CSS transitions do not fulfil your use case, because (for example) you want to chain two animations together, use multiple stops, iterations, or in some other way exploit the additional power animations grant you.
I've not found any way to trigger a CSS animation specifically on mouse-out without using JavaScript to attach "over" and "out" classes. Although you can use the base CSS declaration trigger an animation when the :hover ends, that same animation will then run on page load. Using "over" and "out" classes you can split the definition into the base (load) declaration and the two animation-trigger declarations.
The CSS for this solution would be:
.class {
/* base element declaration */
}
.class.out {
animation-name: out;
animation-duration:2s;
}
.class.over {
animation-name: in;
animation-duration:5s;
animation-iteration-count:infinite;
}
#keyframes in {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
#keyframes out {
from {
transform: rotate(360deg);
}
to {
transform: rotate(0deg);
}
}
And using JavaScript (jQuery syntax) to bind the classes to the events:
$(".class").hover(
function () {
$(this).removeClass('out').addClass('over');
},
function () {
$(this).removeClass('over').addClass('out');
}
);
Creating a reversed animation is kind of overkill to a simple problem. What you need is:
animation-direction: reverse
However, this won't work on its own because animation spec forgot to add a way to restart the animation, so here is how you do it with the help of JS
let item = document.querySelector('.item')
// play normal
item.addEventListener('mouseover', () => {
item.classList.add('active')
})
// play in reverse
item.addEventListener('mouseout', () => {
item.style.opacity = 0 // avoid showing the init style while switching the 'active' class
item.classList.add('in-active')
item.classList.remove('active')
// force dom update
setTimeout(() => {
item.classList.add('active')
item.style.opacity = ''
}, 5)
item.addEventListener('animationend', onanimationend)
})
function onanimationend() {
item.classList.remove('active', 'in-active')
item.removeEventListener('animationend', onanimationend)
}
#keyframes spin {
0% {
transform: rotateY(0deg);
}
100% {
transform: rotateY(180deg);
}
}
div {
background: black;
padding: 1rem;
display: inline-block;
}
.item {
/* because span cant be animated */
display: block;
color: yellow;
font-size: 2rem;
}
.item.active {
animation: spin 1s forwards;
animation-timing-function: ease-in-out;
}
.item.in-active {
animation-direction: reverse;
}
<div>
<span class="item">ABC</span>
</div>
we can use requestAnimationFrame to reset animation and reverse it when browser paints in next frame.
Also use onmouseenter and onmouseout event handlers to reverse animation direction
As per
Any rAFs queued in your event handlers will be executed in the ​same
frame​. Any rAFs queued in a rAF will be executed in the next frame​.
function fn(el, isEnter) {
el.className = "";
requestAnimationFrame(() => {
requestAnimationFrame(() => {
el.className = isEnter? "in": "out";
});
});
}
.in{
animation: k 1s forwards;
}
.out{
animation: k 1s forwards;
animation-direction: reverse;
}
#keyframes k
{
from {transform: rotate(0deg);}
to {transform: rotate(360deg);}
}
<div style="width:100px; height:100px; background-color:red"
onmouseenter="fn(this, true)"
onmouseleave="fn(this, false)"
></div>
Would you be better off having just the one animation, but having it reverse?
animation-direction: reverse
Using transform in combination with transition works flawlessly for me:
.ani-grow {
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
-ms-transition: all 0.5s ease;
transition: all 0.5s ease;
}
.ani-grow:hover {
transform: scale(1.01);
}
I've put together a CodePen with a CSS-only fix and one with 2 lines of jQuery to fix the on-page load issue. Continue reading to understand the 2 solutions in a simpler version.

If you are searching how to do this with CSS only, Xaltar's answer is simple, straightforward, and is the correct solution. The only downside is that the animation for the mouse out will play when the page loads. This happens because to make this work, you style your element with the OUT animation and the :hover with the IN animation.
svg path{
animation: animateLogoOut 1s;
}
svg:hover path{
animation: animateLogoIn 1s;
}
#keyframes animateLogoIn {
from {stroke-dashoffset: -510px;}
to {stroke-dashoffset: 0px;}
}
#keyframes animateLogoOut {
from {stroke-dashoffset: 0px;}
to {stroke-dashoffset: -510px;}
}
Some people found this solution to be useless as it played on page load. For me, this was the perfect solution. But I made a Codepen with both solutions as I will probably need them in the near future.
If you do not want the CSS animation on page load, you will need to use a tiny little script of JS that styles the element with the OUT animation only after the element has been hovered for the first time. We will do this by adding a class of .wasHovered to the element and style the added class with the OUT Animation.
jQuery:
$("svg").mouseout(function() {
$(this).addClass("wasHovered");
});
CSS:
svg path{
}
svg.wasHovered path{
animation: animateLogoOut 1s;
}
svg:hover path{
animation: animateLogoIn 1s;
}
#keyframes animateLogoIn {
from {stroke-dashoffset: -510px;}
to {stroke-dashoffset: 0px;}
}
#keyframes animateLogoOut {
from {stroke-dashoffset: 0px;}
to {stroke-dashoffset: -510px;}
}
And voila! You can find all of this and more on my codepen showing in detail the 2 options with an SVG logo hover animation.

Have tried several solutions here, nothing worked flawlessly; then Searched the web a bit more, to find GSAP at https://greensock.com/ (subject to license, but it's pretty permissive); once you reference the lib ...
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.2.4/gsap.min.js"></script>
... you can go:
var el = document.getElementById('divID');
// create a timeline for this element in paused state
var tl = new TimelineMax({paused: true});
// create your tween of the timeline in a variable
tl
.set(el,{willChange:"transform"})
.to(el, 1, {transform:"rotate(60deg)", ease:Power1.easeInOut});
// store the tween timeline in the javascript DOM node
el.animation = tl;
//create the event handler
$(el).on("mouseenter",function(){
//this.style.willChange = 'transform';
this.animation.play();
}).on("mouseleave",function(){
//this.style.willChange = 'auto';
this.animation.reverse();
});
And it will work flawlessly.
Try this:
#keyframe in {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
#keyframe out {
from {
transform: rotate(360deg);
}
to {
transform: rotate(0deg);
}
}
supported in Firefox 5+, IE 10+, Chrome, Safari 4+, Opera 12+

How to animate multiple CSS transform properties separately using keyframe animation

I want to animate two (or more) CSS transform properties separately using keyframe animation like this:
#keyframes translatex {
100% {
transform: translateX(100px);
}
}
#keyframes rotatez {
100% {
transform: rotateZ(80deg);
}
}
HTML:
<div class="rect"></div>
The translatex animation should start with a 0s delay and last for 5 seconds. The rotatez animation should start with a 1s delay and last for 3 seconds. The .rect element starts moving, then after 1 second it starts rotating, then after 3 seconds it stops rotating and after 1 more second it finishes its movement.
Apply animation:
.rect {
animation-name: translatex, rotatez;
animation-duration: 5s, 3s;
animation-timing-function: ease, ease-in-out;
animation-delay: 0s, 1s;
animation-direction: forward, forward;
}
The problem is that only the rotatez animation is applied.
Are there ways to implement the animation using only CSS, such as keyframe animation or transitions, or do I need JavaScript and requestAnimationFrame?
Yes, it is possible. Instead of calling two animation-names, create only one animation with both actions inside:
#keyframes translateXandZ {
100% {
transform: translateX(100px) rotateZ(80deg);
}
}
Look at Google's "Animate your HTML5" presentation.
Here is a workaround, even though it is a bit of a coarse version:
#-webkit-keyframes translateXandZ {
0% {-webkit-transform: translateX(0px) rotateZ(0deg);}
2% {-webkit-transform: translateX(1px) rotateZ(0deg);}
5% {-webkit-transform: translateX(3px) rotateZ(0deg);}
20% {-webkit-transform: translateX(20px) rotateZ(0deg);}
80% {-webkit-transform: translateX(80px) rotateZ(80deg);}
95% {-webkit-transform: translateX(97px) rotateZ(80deg);}
98% {-webkit-transform: translateX(99px) rotateZ(80deg);}
100% {-webkit-transform: translateX(100px) rotateZ(80deg);}
}
Your animation is linear, but to make it ease-in-out, I played with the beginning and ending of the animation. It's still not perfect, but this is the only way I see how you could get what you want.

-webkit-animation-fill-mode in safari

i am using keyframes to scale an element on my webpage. The problem is that the animation is running perfectly in chrome but its not running in safari. I am providing values at 0% , 80% and 100% in keyframes and everytime the animation ends it goes back to the properties defined at 80% and not 100%. i also used fill-mode to stop animation at last frame but still got no solution.
#-webkit-keyframes leftpageanim {
0%{ -webkit-transform:scale(1);
bottom:-26px;
}
80%{
-webkit-transform:scale(1.8) ; bottom:140px;
}
100%
{
-webkit-transform:scale(1.7); bottom:120px; }
}
after the animation ends its again reverting back to properties of 80%
I did some changes in the code. Look at this jsfiddle. The animation now stops at 100%. That's what you wanted, right?
from:
.animator {
-webkit-animation-name: leftpageanim;
-webkit-animation-iteration-count: 1;
-webkit-animation-timing-function: linear;
-webkit-animation-duration: 5s;
to:
.animator {
-webkit-animation: leftpageanim 5.0s ease-in-out forwards;
-webkit-animation-iteration-count: 1;
