How to use a subset of animation.css animations? - css

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>

Can I make the animation-timing-function affect the whole animation rather than each step of the animation? [duplicate]

This question already has answers here:
Is there a way for animation-timing-function to apply to the entire animation instead of each keyframe?
(4 answers)
Closed 4 years ago.
I have recently been playing a lot with CSS animations. The biggest issue I've had with CSS animations is the animation-timing-function. My issue with this is that the function is applied between each section of the keyframes. What I mean is that if I have a multi-step animation acting on a div:
#keyframes moveProjectTop{
0%{
transform: translateX(0px) translateY(0px) rotateZ(0deg);
}
50%{
transform: translateX(125px) translateY(30px) rotateZ(30deg);
}
100%{
transform: translateX(250px) translateY(60px) rotateZ(0deg);
}
}
What I want from this kind of transformation is for the translation motion to have a bouncing effect, but I want the rotation not to. I don't think this is possible with CSS.
I have been led to believe this because:
1: Transformations can't be split over two animations which means that all transformations have to be under 1 keyframes animation.
2: Animation-timing-functions apply between each step.
I think the solution would have to do with my second detail. Is there a way to have a timing-function apply over a whole animation rather than between each step (between two percentages). The other solution would be if there was a way to apply a different timing function between each step, as in if I could have ease-in apply between 0%-50% and ease-out apply between 50%-100%, then this would imitate an ease-in-out function.
Does anyone have a suggestion on how I could smooth animations in one of these two ways?
An idea is to split the animation and instead of translation you can use top/left then you can easily control each one alone:
.box {
width:60px;
height:60px;
background:red;
position:relative;
animation: bounce 2s infinite linear alternate,
move 2s infinite ease-in alternate;
}
#keyframes bounce{
0%{
transform:rotateZ(0deg);
}
50%{
transform: rotateZ(30deg);
}
100%{
transform:rotateZ(0deg);
}
}
#keyframes move{
0%{
top:0px;
left:0px;
}
50%{
top:125px;
left:30px;
}
100%{
top:250px;
left:60px;
}
}
<div class="box">
</div>

Rotate animation and translate?

The rotate animation won't work with translate. I get, that I have to put translate in the same property with the rotate, but how is this possible when using keyframes? Code is like so:
#-webkit-keyframes rotating {
from{
-webkit-transform: rotate(0deg);
}
to{
-webkit-transform: rotate(360deg);
}
}
#keyframes rotating {
from{
transform: rotate(0deg);
}
to{
transform: rotate(360deg);
}
}
img{
-webkit-transform:translate(-50%,-50%);
transform:translate(-50%,-50%);
-webkit-animation: rotating 2s linear infinite;
animation: rotating 2s linear infinite;
position:absolute;
top:50%;
left:50%;
}
This will make the rotation, but it disables the translate. If I put the translate into the rotating animation, the translate is being animated as well(ofcourse).
The 2022+ answer
You can work around this by using individual property transforms which have pretty good browser support.
In short, use the properties like scale, translate, etc. instead of transform.
Side note: You don't need browser-specific properties for anything related to transforms or animations these days.
The original 2014 answer
The issue is that the transform in the animation is overriding the default transform:translate. In this case, you can combine them in the animation itself but it has to be hard coded.
#keyframes rotating {
from {
transform: translate(-50%,-50%) rotate(0deg);
}
to {
transform: translate(-50%,-50%) rotate(360deg);
}
}
If you need it to be dynamic, you can nest it in an element and animate one while not affecting the other - most likely translate the parent and rotate the child.
If you absolutely cannot have more than one element, you can affect the transform matrix for the element using JavaScript, in which case using an animation library like GSAP would be advantageous.

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; }
https://codepen.io/lafland/pen/MoEaoG
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);
}
}

Need help with understanding CSS3 animations

I am trying to learn animations in CSS3 but Im stuck with all the documentation out there. I have this code:
h1{
-webkit-animation: moveDown 1.s ease-in-out .6s backwards;
-moz-animation: moveDown 1s ease-in-out 0.6s backwards;
-o-animation: moveDown 1s ease-in-out 0.6s backwards;
-ms-animation: moveDown 1s ease-in-out 0.6s backwards;
animation: moveDown 1s ease-in-out 0.6s backwards;
}
#-webkit-keyframes moveDown{
0% {
-webkit-transform: translateY(-300px);
opacity: 0;
}
100% {
-webkit-transform: translateY(0px);
opacity: 1;
}
}
#-moz-keyframes moveDown{
0% {
-moz-transform: translateY(-40px);
opacity: 0;
}
100% {
-moz-transform: translateY(0px);
opacity: 1;
}
}
#-o-keyframes moveDown{
0% {
-o-transform: translateY(-40px);
opacity: 0;
}
100% {
-o-transform: translateY(0px);
opacity: 1;
}
}
I understand that webkit-animation - animation is the call for each browser.
I dont understand the modeDown. Is that like a variable?
1s is the length of the animations?
ease-in-out I dont understand
.6s is the delay
I dont get the backwards nor am able to find any info on it
Is this for the timing sequence?
#-moz-keyframes moveDown{
0% {
-moz-transform: translateY(-40px);
opacity: 0;
}
100% {
-moz-transform: translateY(0px);
opacity: 1;
}
Ive read this, this and this. Does someone mind explaining this better to me?
}
I dont understand the modeDown. Is that like a variable?
The animation moveDown starts at opacity:0 and -moz-transform:translateY(-40px) and finishes at opacity: 1 and -moz-transform: translateY(0px). This means that it starts completely transparent and shifted 40 pixels above where it normally is and ends at its regular positioning and fully opaque.
#-moz-keyframes moveDown{
0% {
-moz-transform: translateY(-40px);
opacity: 0;
}
100% {
-moz-transform: translateY(0px);
opacity: 1;
}
}
1s is the length of the animations?
Yes.
ease-in-out I dont understand
ease-in-out is an animation-timing-function, this specifies how to transition from 0% to 100% (or the other way). Ease in out will each in and each out of the animation so the change won't be so abrupt, another example is linear which will change in a completely uniform fashion.
There is a handy chart on this page that explains the difference better than words.
.6s is the delay
Yes.
I dont get the backwards nor am able to find any info on it
backwards and forwards are used for animation-fill-mode which says switch direction the animation should go. If forwards is chosen then the animation will run from 0% (transparent) to 100% (opaque), if backwards is chosen then the animation will run from 100% to 0%.

It's often better to read the actual working drafts (or recommendations) from the W3C, since they provide complete information:
I dont understand the modeDown. Is that like a variable?
You could say so, however variables are usually mutable, while moveDown is simply an identifier for an animation. So it's simply the animation's name:
Keyframes are specified using a specialized CSS at-rule. A #keyframes rule consists of the keyword "#keyframes", followed by an identifier giving a name for the animation (which will be referenced using ‘animation-name’), followed by a set of style rules (delimited by curly braces). [source]
1s is the length of the animations?
ease-in-out I dont understand
.6s is the delay
The animation property is a shorthand for several animation-* properties at once:
<single-animation> = <single-animation-name> || <time> || <single-animation-timing-function> || <time> || <single-animation-iteration-count> || <single-animation-direction> || <single-animation-fill-mode> || <single-animation-play-state>
As you can see the first property is the animation's name (see above), the second the actual length, the third one is the timing-function, in your case ease-in-out. This is basically a bezier-curve which modifies the timing. For example you want to speed up the animation at the beginning and the end, and have a more linear behaviour in the middle.
.6s is indeed the delay between the animations.
I dont get the backwards nor am able to find any info on it
Have a look at animation-fill-mode:
If the value for ‘animation-fill-mode’ is ‘backwards’, then the animation will apply the property values defined in the keyframe that will start the first iteration of the animation, during the period defined by ‘animation-delay’. These are either the values of the ‘from’ keyframe (when ‘animation-direction’ is ‘normal’ or ‘alternate’) or those of the ‘to’ keyframe (when ‘animation-direction’ is ‘reverse’ or ‘alternate-reverse’).

Have CSS3 spin start slow then end slow?

This is not a question that can be solved by using ease-in.
If I have an element that I want to spin in CSS3 for a certain amount of time, but that starts off slow and ends slow, how can I do this?
CSS
#-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
}
div{
background-image:-webkit-radial-gradient(center, ellipse cover, rgba(0,0,0,1) 0%,rgba(51,51,51,1) 20%,rgba(0,0,0,1) 20%,rgba(51,51,51,1) 40%,rgba(0,0,0,1) 40%,rgba(51,51,51,1) 60%,rgba(0,0,0,1) 60%,rgba(51,51,51,1) 80%,rgba(0,0,0,1) 80%,rgba(51,51,51,1) 100%);
width: 200px;
height: 200px;
-webkit-animation-name: spin;
-webkit-animation-duration: 2s;
-webkit-animation-iteration-count: 60.5;
-webkit-animation-timing-function: ease-in;
}
HTML
<div></div>
I can't seem to figure out how to do this. My animation runs for a total of 121 seconds, since it takes 2 seconds for one spin to complete, so 60.5 spins will take a total of 121 seconds (if my math is incorrect, please tell me). This works fine, except that I want the div to start spinning off slow, then completed all 59 rotations, then end slow for the last one.
I'd like to use pure CSS for this, if possible.
Sorry that I don't have a JSFiddle...
Edit: I used a relative solution in my experiment: CSS3 Clock, could that count as a half fiddle? :D
Edit #2: JSFiddle provided by #Charlie: http://jsfiddle.net/7DPnc
If it really has to be pure CSS, I would suggest wrapping 3 divs together and spin them separately:
CSS
div.first_round
{
-webkit-animation-duration:3s;
-webkit-animation-iteration-count:1;
}
div.last_round
{
-webkit-animation-duration:3s;
-webkit-animation-iteration-count:1.5;
-webkit-animation-delay:100s; /* you'll have to do the math */
}
div.main_round
{
-webkit-animation-duration:2s;
-webkit-animation-delay:3s;
-webkit-animation-iteration-count:59;
-webkit-animation-timing-function:linear;
}
HTML
<div class="first_round">
<div class="last_round">
<div class="main_round">
</div>
</div>
</div>
Or if you don't mind using a little JS, listen to animationend event...
You need 60 spins in 120 seconds right?
Lets first change the iteration count to 1.
-webkit-animation-iteration-count:1;
and the duration to 120 seconds
-webkit-animation-duration: 120s;
Now set the amount of spins. (360deg x 60spins)
#-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(21600deg); }
}
And now we'll modify that to set the timing. (shave a rotation off each side, add to new section)
#-webkit-keyframes spin {
10% { -webkit-transform: rotate(360deg); }
90% { -webkit-transform: rotate(20880deg); }
100% { -webkit-transform: rotate(21600deg); }
}
Lastly, we set the easing function to linear in order to avoid the stop that will occur between keyframe sections if you use a curve. (replace with ease, ease-out, etc to see what I mean)
-webkit-animation-timing-function: linear;
You can easily tweak the timing by changing duration, and the keyframe percentages.
