Is there a way to pulsate opacity from 0 to 1 (repeat) slowly with a CSS3 keyframes transformation, infinitely? Or does this require jQuery or Javascript with a transition opacity inside a class that is toggled on an interval?
I'm trying to work it into my orbit transformations (below). (I'm working on a live wallpaper background effect with multiple opaque images floating in a sidebar image on an installer application I'm building in Objective C.)
.orbit1
{
animation: myOrbit 200s linear infinite;
}
.orbit2
{
animation: myOrbit2 200s linear infinite;
}
#keyframes myOrbit1
{
from { transform: rotate(0deg) translateX(150px) rotate(0deg) }
to { transform: rotate(360deg) translateX(150px) rotate(-360deg) }
}
#keyframes myOrbit2
{
from { transform: rotate(360deg) translateX(250px) rotate(-360deg) }
to { transform: rotate(0deg) translateX(250px) rotate(0deg) }
}
You can do it by adding multiple animations to the element, for example:
.orbit1
{
/* added for example reasons */
position :absolute;
top: 50%;
left: 50%;
margin-top: -100px;
margin-left: -100px;
width: 200px;
height: 200px;
background: red;
/* ---------- */
animation: myOrbit1 20s linear infinite, Pulsate 4s linear infinite;
}
#keyframes myOrbit1
{
from { transform: rotate(0deg) translateX(150px) rotate(0deg) }
to { transform: rotate(360deg) translateX(150px) rotate(-360deg) }
}
#keyframes Pulsate {
from { opacity: 1; }
50% { opacity: 0; }
to { opacity: 1; }
}
<div class="orbit1"></div>
I'ved modified some of your parameters (like the speed of the animation and the opacity minimum) and added some spoof styling for the element for the purpose of the example.
Edit
I had originally thought that the multiple rotate() declarations were in error, but #vals informed me why it was there (to create a counter rotation on the object). I've updated the answer, and learned something new.

I am trying to make an Oscillatory animation using css as shown below:
Here's how I have created my animation:
#keyframes rotateFeather {
0% {
transform: rotate(0deg);
}
25% {
transform: rotate(-180deg);
}
50% {
transform: rotate(-90deg);
}
75% {
transform: rotate(90deg);
}
100% {
transform: rotate(180deg);
}
}
Here is my class: (Using sccs)
.logo {
height: 5rem;
transition: all 0.3s ease;
&box {
position: absolute;
top: 4rem;
left: 4rem;
}
&:hover {
animation-name: rotateFeather;
animation-duration: 1s;
animation-iteration-count: infinite;
animation-timing-function: linear;
}
}
Here I am facing this problem: When it reaches 180deg at 100% it abruptly resets to 0 which I want to make smooth.
How is it possible to do the same?
To ensure smooth transition, We need to make sure that transformation at 0 and 100% must match with the original state:
#keyframes rotateFeather {
0% {
transform: rotate(0deg); //-30
transform-origin: bottom;
}
20% {
transform: rotate(-30deg); //-60
transform-origin: bottom;
}
40% {
transform: rotate(0deg); //-30
transform-origin: bottom;
}
60% {
transform: rotate(30deg); // 0
transform-origin: bottom;
}
80% {
transform: rotate(60deg); //30
transform-origin: bottom;
}
100% {
transform: rotate(0deg); //30
transform-origin: bottom;
}
}
This helped me to solve my issue. I am not sure, if I need to add transform-origin in every stage, if someone can elaborate better on that, that would be helpful.
Here's a simplified version of your latest animation code (with a Codepen to see it in action):
#keyframes rotateFeather {
0% {
transform: rotate(0deg);
}
20% {
transform: rotate(-30deg);
}
80% {
transform: rotate(60deg);
}
100% {
transform: rotate(0deg);
}
}
.logo {
transform-origin: bottom;
&:hover {
animation: rotateFeather 1s linear infinite;
}
}
Some points about the above tweaks:
You don't need transform-origin at every keyframe. You can set it globally.
You can roll all of your animation properties into a single shorthand rule.
You can skip keyframes that are mathematically interpolating where the animation would be going anyway (notice I omitted 40% and 60% above and it looks the same).
You don't need any transition rules on elements that you are animating with keyframes. Unless you're using it for something else, but you want to be careful to avoid attempting to animate the same property on the same element with both animation and transition simultaneously, as it will break the animation in question.
I'm trying to make a css rotation animation that has different speeds at different degree points.
Here is the animation I'm trying to make:
Here is a Pen of what I currently have and below is the code:
img {
width: 125px;
}
body {
text-align: center;
}
#loading {
-webkit-animation: slow 1.5s linear 1.5s, fast 1s linear 1s, slow2 1s linear 1s;
-webkit-animation-iteration-count: infinite;
}
#-webkit-keyframes slow {
from {
-webkit-transform: rotate(0deg)
}
to {
-webkit-transform: rotate(90deg)
}
}
#-webkit-keyframes fast {
from {
-webkit-transform: rotate(91deg)
}
to {
-webkit-transform: rotate(270deg)
}
}
#-webkit-keyframes slow2 {
from {
-webkit-transform: rotate(271deg)
}
to {
-webkit-transform: rotate(359deg)
}
}
<img id="loading" src="https://i.imgur.com/VpLRlbZ.png">
So, in the example you provided, the effect is only done by modifying the animation-timing-function css property.
Then you'll have only one animation
div {
width:100px;
height:100px;
background:red;
animation:rotate 3s infinite;
animation-timing-function: cubic-bezier(1,0,.5,1);
}
#-webkit-keyframes rotate {
from { -webkit-transform: rotate(0deg) }
to { -webkit-transform: rotate(360deg) }
}
<div></div>
You can find more informations here : https://callmenick.com/dev/level-up-animations-cubic-bezier/
But the point is, use only one animation and modify speed at different angles value modifying this animation-timing-function.
EDIT Added a closer cubic bezier timing function thanks to #SirExotic comment.
You can just divide the animation keyframes into several ones, and adjust the percentages of each to set the relative speeds:
The natural percentage for 90deg would be 25% . Any value higher than that will make this part slower
img {
width: 125px;
}
body {
text-align: center;
}
#loading {
animation: rotate 4s linear infinite;
}
#keyframes rotate {
0% {
transform: rotate(0deg)
}
40% {
transform: rotate(90deg)
}
60% {
transform: rotate(270deg)
}
100% {
transform: rotate(360deg)
}
}
<img id="loading" src="https://i.imgur.com/VpLRlbZ.png">
I have two transform operations (rotate and translate) and I want to make transition for translate only (rotate have to be instant).
Some suggestions? I prefer pure css.
Use keyframes to reach your desired effect, in addition to animation-fill-mode to keep the computed styles when the animation is finished.
.object {
width: 50px;
height: 50px;
background-color: #F00;
animation-fill-mode: forwards;
}
.object:hover {
animation: move 1s;
animation-fill-mode: forwards;
}
#keyframes move {
0% {
transform: translateY(0px) rotate(0deg);
}
1% {
transform: rotate(45deg);
}
100% {
transform: translateY(25px) rotate(45deg);
}
}
<div class="object"></div>
Please tell me how to make a "smooth" animations.
I have the keyframes, which describes the behavior of the animation in the download. And at Hover, connects the other keyframes (animation and changes its course).
Between them the change occurs sharpness.
Here is an example of field http://jsfiddle.net/g4wvqrL8/
.icon-1 {
width: 3em;
height: 3em;
margin: 85px auto;
animation: pull 3s infinite reverse ease-in-out
}
.icons {
width:80%;
margin: 0 auto;
height:90px;
}
.icons:hover {
animation: rotate360 4s infinite reverse cubic-bezier(0.4, 0, 1, 1);
}
#keyframes pull {
0% {
transform: translateY(0px);
}
50% {
transform: translateY(-55px);
}
100%{
transform: translateY(0px);
}
}
#keyframes rotate360 {
0% {
transform: rotate(0deg) translateX(30px);
}
100% {
transform: rotate(360deg) translateX(30px);
}
}
Question: how at different keyframes at Hover to make the smooth transition of 2 types of animation?
I tried to make transition (shifts them to the desired trajectory at Hover and start a new animation, but smooth still was not).
Or how to start the animation with a place to stay until this animation ??
Prompt, all thanks in advance!
I have a background image that has an arrow that points to the right. When a user clicks on the button, the selected state changes the arrow to point down (using a different background position in my image sprite).
Is there anyway to animate this using CSS3 so once the button is clicked and jQuery assigns it a "selected" class, it will rotate in an animation (only 90 degrees) from the right to down? (preferably using the single image/position with the arrow that points to the right)
I'm unsure as to whether transform or key animation frames need to be used.
you could use the ::after (or ::before) pseudo-element, to generate the animation
div /*some irrelevant css */
{
background:-webkit-linear-gradient(top,orange,orangered);
background:-moz-linear-gradient(top,orange,orangered);
float:left;padding:10px 20px;color:white;text-shadow:0 1px black;
font-size:20px;font-family:sans-serif;border:1px orangered solid;
border-radius:5px;cursor:pointer;
}
/* element to animate */
div::after /* you will use for example "a::after" */
{
content:' ►'; /* instead of content you could use a bgimage here */
float:right;
margin:0 0 0 10px;
-moz-transition:0.5s all;
-webkit-transition:0.5s all;
}
/* actual animation */
div:hover::after /* you will use for example "a.selected::after" */
{
-moz-transform:rotate(90deg);
-webkit-transform:rotate(90deg);
}
HTML:
<div>Test button</div>
in your case you will use element.selected class instead of

hope this helps
Here is a rotating css class that I have used to spin a background image:
.rotating {
-webkit-animation: rotating-function 1.25s linear infinite;
-moz-animation: rotating-function 1.25s linear infinite;
-ms-animation: rotating-function 1.25s linear infinite;
-o-animation: rotating-function 1.25s linear infinite;
animation: rotating-function 1.25s linear infinite;
}
#-webkit-keyframes rotating-function {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(360deg);
}
}
#-moz-keyframes rotating-function {
from {
-moz-transform: rotate(0deg);
}
to {
-moz-transform: rotate(360deg);
}
}
#-ms-keyframes rotating-function {
from {
-ms-transform: rotate(0deg);
}
to {
-ms-transform: rotate(360deg);
}
}
#-o-keyframes rotating-function {
from {
-o-transform: rotate(0deg);
}
to {
-o-transform: rotate(360deg);
}
}
#keyframes rotating-function {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
