I have a bounce animation occur on hover on my page (on an image of an arrow). However, if the cursor is near the top edge, it will generally jitter, due to the change of the position of the content area from what I can gather. The image will move, bringing your mouse out of the hover area, resetting the image position abruptly, and repeating until you move the mouse.
Does anyone have any idea how to fix this? Can be CSS/Javascript/some other library, doesn't matter to me.
.arrow-main {
position: absolute;
left: 0;
right: 0;
bottom: 1%;
margin-left: auto;
margin-right: auto;
margin-bottom: 10px;
width: 90px;
}
.bounce:hover {
-webkit-animation:bounce .9s infinite;
-moz-animation:bounce .9s infinite;
-o-animation:bounce .9s infinite;
animation:bounce .9s infinite;
}
#-webkit-keyframes bounce {
0% { bottom:10px; }
50% { bottom:0px; }
100% { bottom:10px; }
}
#-moz-keyframes bounce {
0% { bottom:10px; }
50% { bottom:0px; }
100% { bottom:10px; }
}
#-o-keyframes bounce {
0% { bottom:10px; }
50% { bottom:0px; }
100% { bottom:10px; }
}
#keyframes bounce {
0% { bottom:10px; }
50% { bottom:0px; }
100% { bottom:10px; }
}
I actually made a codepen to try and illustrate the issue, but it doesn't jitter at all... I'm using Chrome.
EDIT: Just tried the codepen again, and it jitters as it should.
EDIT 2: I modified the codepen to try out the comments so far, and if you hold your cursor near the bottom of the arrow img, you should get an idea of what I am trying to combat.

I'm trying to build a puzzle game website. I'm using webkit animation to rotate (and translate) two images.
My plan is to have rotating gears attached to the left and right edge of my page, offset in a way that only half of each image is shown at a time.
The animation works fine but
(1) i am unable to pause it, and
(2) depending on window size the images are moved out of view (with an automatic scrollbar popping up) or into full view.
The setup is pretty simple:
I have 3 divs: one bar at the top with 100% width and two divs with 50% width below as containers for my images.
I might need to add more below or in between the two divs down the road but for now a solution for this would be good enough^^
For the animation i have a pseudo button on each side which adds a pause class to my images.
HTML
<div id="div-left">
<p>Hey this is the left div</p>
<img src="images/zahnrad.png" alt="zahnrad" id="image1">
<p id="pausebtn1" onclick="pause1()">pause</p>
</div>
<div id="div-right">
<p>hey this is the right div</p>
<img src="images/zahnrad.png" alt="zahnrad" id="image2">
<p id="pausebtn2" onclick="pause2()">pause</p>
</div>
CSS
#image1{
-webkit-animation: rotation-left 30s infinite linear;
}
#image1.paused1::-webkit-progress-value{
-webkit-animaion-play-state:paused;
animaion-play-state:paused;
}
#image2{
align: right;
-webkit-animation: rotation-right 30s infinite linear;
}
#image2.paused2::-webkit-progress-value{
-webkit-animaion-play-state:paused;
animaion-play-state:paused;
}
/* Animations */
#-webkit-keyframes rotation-left{
from {
-webkit-transform: translate(-50%,0px) rotate(0deg);
}
to{
-webkit-transform: translate(-50%,0px) rotate(359deg);
}
}
#-webkit-keyframes rotation-right{
from {
-webkit-transform:translate(+50%,0px) rotate(0deg);
}
to{
-webkit-transform:translate(+50%,0px) rotate(-359deg);
}
}
Javascript
function pause1() {
console.log("pause img 1");
document.getElementById('image1').classList.toggle("paused1");
}
function pause2() {
console.log("pause img 2");
document.getElementById('image2').classList.toggle("paused2");
}
So to sum it all up:
I have two images in the wrong places. They are animated. My two buttons are working but trying to pause the animation by adding a paused class doesn't function.
Any help would be appreciated and i'll see if i can add images later
You shouldn't be targeting ::-webkit-progress-value, that's for <progress> elements. Just toggle the class onto the element:
button.addEventListener('click', function () {
square.classList.toggle('paused');
});
#square {
animation: rotate 1s infinite;
background: lightblue;
border: 1px solid black;
height: 100px;
left: 50px;
position: absolute;
top: 50px;
width: 100px;
}
#square.paused {
animation-play-state: paused;
}
#keyframes rotate {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
<button id="button">Pause/Resume</button>
<div id="square">Rotate</div>
I'm trying to animate an element to slowly move from left to right a small distance and do it in a smooth way but the result is not very good.
Here is what I have so far:
.animate_sideways{animation:sideways 5s linear infinite; animation-timing-function: ease-in, ease-in-out;};
#keyframes sideways {
50% {
transform: translateX(30px);
}
100% {
transform: translateX(-30px);
}
}
I think the problem is related to the missing start point in the keyframes for the transform attribute.
A minor tweak to your code should correct the issue.
A different animation-timing-function value or time frame (less that 5s for example) may suit you better as well.
.contain { width:100% }
.animate_sideways {
width:40px;
height:40px;
background:#482;
animation:sideways 5s linear infinite;
animation-timing-function:ease-in, ease-in-out;
}
#keyframes sideways {
0% { transform: translateX(-30px) }
50% { transform: translateX(30px) }
100% { transform: translateX(-30px) }
}
<div class="contain">
<div class="animate_sideways"></div>
</div>
I have 2 elements that overlap each other, on hover I want to animate the bottom element out to the right and then move back left but on top of the other element, on mouseleave I then want it to animate back to its default state. I've got something working only the opacity issue is making it quite buggy and not as smooth as I'd have liked...

I forked your pen. I just added some more brekpoints to the animation and changed the css slightly on the hover event. I think this is what you want (link to forked pen and css below)
https://codepen.io/ecglover8/pen/qVKBxX
body {
background:#cacaca;
}
.sector-card {
position:relative;
width:50%;
.sector-panel {
width:50%;
display:block;
height:300px;
&__information {
background:#fff;
z-index:1;
position:relative;
}
&__study {
background-size:cover;
z-index:0;
position:absolute;
top:15%;
right:25%;
}
}
&:hover {
.sector-panel__study {
animation:moveFront 2s forwards;
z-index:3;
}
}
}
#keyframes moveFront {
0% { z-index:-1; right:25%; }
49% {z-index:-1;right:0;}
50% {z-index:3;right:0;}
100% {right:25%;}
}
Unfortunately, you can't transition z-index. One thing you can do is transition opacity to make it appear smoother.
Something like:
#keyframes moveFront {
0% { right:25%; opacity: 0; }
100% { right:0%;z-index:3; opacity: 1; }
}
Hope this helps!
Well, the CSS only solution i got was creating another animation that will play when the mouse leave. It does, obviously, an animation when you load the page but thats because it is a CSS only solution:
https://codepen.io/anon/pen/YEvPNB?editors=1100
I just copied the same animation and put the values on backwards.
#keyframes moveBack {
100% {
z-index: -1;
right: 25%;
top: 5%;
}
50% {
z-index: -1;
right: 0;
}
49% {
z-index: 3;
right: 0;
top: 10%;
}
0% {
z-index: 3;
right: 25%;
top: 5%;
}
}
And then i just put the naimation on your .sector-panel__study.
&__study {
background-size: cover;
z-index: 0;
position: absolute;
top: 5%;
right: 25%;
animation: moveBack 1s forwards; // HERE
}
Hope this helps.
Well I managed to do the back to position part but it becomes a bit buggy because there is not opposite to :hover, so this will execute when the div is created.
Changed this to the CSS:
body {
background:#cacaca;
}
.sector-panel__study{
opacity: 0.5;
animation:moveBack 2s backwards;
animation-fill-mode: forwards;
}
.sector-card {
position:relative;
width:50%;
.sector-panel {
width:50%;
display:block;
height:300px;
&__information {
background:#fff;
z-index:1;
position:relative;
}
&__study {
background-size:cover;
z-index:0;
position:absolute;
top:15%;
right:25%;
}
}
&:hover {
.sector-panel__study {
animation:moveFront 2s forwards;
animation-fill-mode: forwards;
}
.sector-panel__information {
opacity: 0.5;
z-index: 0;
}
}
}
#keyframes moveFront {
0% { right:25%; }
50% {z-index:3; right:0;}
100% { opacity: 1; right:25%;}
}
#keyframes moveBack {
0% { z-index: 3; Right:25%; opacity:1;}
50% {z-index:0; Right:0;}
100% { opacity: 0.5; Right:25%;}
}
Can put snipped, you will have to copy this css code and test!
I have this .png that I wanted to make it bounce a little every time it detects a scroll movement but I'm not good in javascript and css. I hope you guys can help me
<div class="arrownav bounce">
<a href="" class="logo">
<img src="{{ asset('assets/img/arrow down.png') }}" height="45">
</a>
</div>
I am now using a css that made the image bounce
this is the code:
.bounce {
-webkit-animation:bounce 1s infinite;
-moz-animation:bounce 1s infinite;
-o-animation:bounce 1s infinite;
animation:bounce 1s infinite;
}
#-webkit-keyframes bounce {
0% { bottom:0px; }
50% { bottom:15px; }
100% {bottom:30;}
}
#-moz-keyframes bounce {
0% { bottom:0px; }
50% { bottom:15px; }
100% {bottom:30;}
}
#-o-keyframes bounce {
0% { bottom:0px; }
50% { bottom:15px; }
100% {bottom:30;}
}
#keyframes bounce {
0% { bottom:0px; }
50% { bottom:15px; }
100% {bottom:30;}
}
The first thing I noticed is the missing unit in all #keyframes, right here:
100% {bottom:30;}
This should be:
100% { bottom:30px; }
You've used the bottom style in you animation, which is perfectly fine, but in order for it to work the element's position needs to be either relative, absolute or fixed (more here).
.bounce {
position: relative;
-webkit-animation: bounce 1s infinite;
-moz-animation: bounce 1s infinite;
-o-animation: bounce 1s infinite;
animation: bounce 1s infinite;
}
Here's a working fiddle.
Bonus
Another way to change the element's position in the animation is the transform style, instead of using bottom. When you use transform, you don't need position: relative;.
#keyframes bounce {
0% {
transform: translateY(0px);
}
50% {
transform: translateY(-15px);
}
100% {
transform: translateY(-30px);
}
}

I'm creating a marquee effect with CSS3 animation.
#caption {
position: fixed;
bottom: 0;
left: 0;
font-size: 20px;
line-height: 30px;
height:30px;
width: 100%;
white-space: nowrap;
-moz-animation: caption 50s linear 0s infinite;
-webkit-animation: caption 50s linear 0s infinite;
}
#-moz-keyframes caption {
0% { margin-left:120%; } 100% { margin-left:-4200px; }
}
#-webkit-keyframes caption {
0% { margin-left:120%; } 100% { margin-left:-4200px; }
}
<div id="caption">
The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. the quick brown fox jumps over the lazy dog.
</div>
Now I can get the basic marquee effect, but the code is too specific for this demo.
Is there a way to avoid using specific values like margin-left:-4200px;, so that it can adapt text in any length?
Here is a similar demo: http://jsfiddle.net/jonathansampson/XxUXD/ that uses text-indent but still with specific values.
With a small change of the markup, here's my approach (I've just inserted a span inside the paragraph):
.marquee {
width: 450px;
margin: 0 auto;
overflow: hidden;
box-sizing: border-box;
}
.marquee span {
display: inline-block;
width: max-content;
padding-left: 100%;
/* show the marquee just outside the paragraph */
will-change: transform;
animation: marquee 15s linear infinite;
}
.marquee span:hover {
animation-play-state: paused
}
#keyframes marquee {
0% { transform: translate(0, 0); }
100% { transform: translate(-100%, 0); }
}
/* Respect user preferences about animations */
#media (prefers-reduced-motion: reduce) {
.marquee span {
animation-iteration-count: 1;
animation-duration: 0.01;
/* instead of animation: none, so an animationend event is
* still available, if previously attached.
*/
width: auto;
padding-left: 0;
}
}
<p class="marquee">
<span>

No hardcoded values — dependent on paragraph width — have been inserted.
The animation applies the CSS3 transform property (use prefixes where needed) so it performs well.
If you need to insert a delay just once at the beginning then also set an animation-delay. If you need instead to insert a small delay at every loop then try to play with an higher padding-left (e.g. 150%)
Based on the previous reply, mainly #fcalderan, this marquee scrolls when hovered, with the advantage that the animation scrolls completely even if the text is shorter than the space within it scrolls, also any text length takes the same amount of time (this may be a pros or a cons) when not hovered the text return in the initial position.
No hardcoded value other than the scroll time, best suited for small scroll spaces
.marquee {
width: 100%;
margin: 0 auto;
white-space: nowrap;

display: inline-flex;
}
.marquee span {

flex-basis: 100%;
animation: marquee-reset;
animation-play-state: paused;
}
.marquee:hover> span {
animation: marquee 2s linear infinite;
animation-play-state: running;
}
#keyframes marquee {
0% {
transform: translate(0%, 0);
}
50% {
transform: translate(-100%, 0);

50.001% {

}
100% {
transform: translate(0%, 0);

}
#keyframes marquee-reset {
0% {
transform: translate(0%, 0);
}
}
<span class="marquee">
<span>This is the marquee text (hover the mouse here)</span>
</span>
The accepted answers animation does not work on Safari, I've updated it using translate instead of padding-left which makes for a smoother, bulletproof animation.
Also, the accepted answers demo fiddle has a lot of unnecessary styles.
So I created a simple version if you just want to cut and paste the useful code and not spend 5 mins clearing through the demo.
