I'm attempting to create a pulsing animation of an element using CSS3's transform: scale(x,y). I want the object to endlessly pulse (becoming slightly larger) unless it's hovered over - at which point the current animation should finish (i.e. return to its original size) and cease pulsing until it's no longer being hovered over. I can't even seem to get jQuery's .animate() to work, however.
function pulse() {
$('#pulsate').animate({
transition: 'all 1s ease-in-out',
transform: 'scale(1.05,1.05)'
}, 1500, function() {
$('#pulsate').animate({
transition: 'all 1s ease-in-out',
transform: 'scale(1,1)'
}, 1500, function() {
pulse();
});
});
}
pulse();
Would using .addClass and .removeClass be better here? .removeClass would do the trick for stopping the animation on .hover(), but I'm unsure on implementation overall.
Try using CSS animations.
#keyframes pulse {
0% {
transform: scale(1, 1);
}
50% {
transform: scale(1.1, 1.1);
}
100% {
transform: scale(1, 1);
}
}
#test {
animation: pulse 1s linear infinite;
}
#-webkit-keyframes pulse {
0% {
-webkit-transform: scale(1, 1);
}
50% {
-webkit-transform: scale(1.1, 1.1);
}
100% {
-webkit-transform: scale(1, 1);
};
}
#keyframes pulse {
0% {
transform: scale(1, 1);
}
50% {
transform: scale(1.1, 1.1);
}
100% {
transform: scale(1, 1);
};
}
#test {
background: red;
width: 20px;
height: 20px;
-webkit-animation: pulse 1s linear infinite;
animation: pulse 1s linear infinite;
}
#test:hover {
-webkit-animation: none;
animation:none;
}
<div id="test"></div>

Struggling to even get started figuring this out, I am working on a website for a friend, here is a one of the pages..
http://sarahboulton.co.uk/livingroom.html
So on refresh it brings up one of four constellations of letters, which shift their constellations using math random.
We were hoping to start applying small animations to the letters.. something along these lines..
.lipbalm {
animation: shake 0.1s;
animation-iteration-count: infinite; }
#keyframes shake {
0% { transform: translate(0px) }
50% { transform: translate(0.5px) }
100% { transform: translate(0px) }
}
But whether these movements could be randomised for each letter, still small movements.. but using something similar to..
$(document).ready(function(){
$('.goldrocks-g').css({'left' : (Math.random() * 250) + 350})
});
..each letter randomises its movement, maybe one ends up on..
#keyframes shake {
0% { transform: translate(0px) }
50% { transform: translate(0.4px) }
100% { transform: translate(0px) }
}
.. and another has..
#keyframes shake {
0% { transform: translate(0px) }
50% { transform: translate(0.1px) }
100% { transform: translate(0px) }
}
and something similar for the speed too? All the letters have their own div, might be easier to view the source of the page to see whats going on !
The way I would approach this problem is by creating the a few variations of your shake class and then assign those classes at random when you are assigning the random constellation.
So something like this:
css
.shake-1{
animation: shake-1 0.3s;
animation-iteration-count: infinite;
}
.shake-2{
animation: shake-2 0.3s;
animation-iteration-count: infinite;
}
.shake-3{
animation: shake-3 0.3s;
animation-iteration-count: infinite;
}
#keyframes shake-1 {
0% { transform: translate(0px) }
50% { transform: translate(2px) }
100% { transform: translate(0px) }
}
#keyframes shake-2 {
0% { transform: translate(0px) }
50% { transform: translate(-2px) }
100% { transform: translate(0px) }
}
#keyframes shake-3 {
0% { transform: translate(0px) }
50% { transform: translate(0px, 2px) }
100% { transform: translate(0px) }
}
html
<div class="dyinglight-d shake-1" style="left: 839.646px; top: 212.011px;">...</div>
<div class="dyinglight-y shake-2" style="left: 959.592px; top: 97.9469px;">...</div>
etc
Here's a codepen I made for you with your site's code to show an example of it working: https://codepen.io/ChrisRArendt/pen/jQXjNa
You may generate CSS style using javaScript to integrate javaScript Math.random() into CSS logic.
For example you can generate 10 keyframes with names shake1 to shake10 with random transform on 50% and append this styles to the header style :
var css;
for (x=1;x=10;x++){
css += '#keyframes shake'+ x.toString() +' {';
css += '0% { transform: translate(0px)}';
css += '50% { transform: translate('+ Math.random() +'px)}';
css += '100% { transform: translate(0px)}';
css += '}';
}
$( "<style>" + css + </style>").appendTo( "head" );
Finally you can assign each keyframe randomly to target divs:
$('.goldrocks-g').each(function(){
(this).css({"animation": "shake" + Math.random()*10+1 +" 0.1s infinite");
})
I think the easiest way to do this would be to have a random feeling shake animation that could be applied to all letters. Then you can randomly apply inline CSS of animation-delay: 100ms or animation-delay: 300ms. That style could be applied differently each time. All letters will be using the same shake animation but will be at different intervals in the animation based on their delay time.
I'm looking for a way to animate a plane flying from off-page onto the page. At the moment, I'm using the code below, which is very clunky and not smooth. Do you know a better way to do this using CSS and HTML? If not, using another method?
.plane-animation{
animation: animationFrames linear 3s;
animation-iteration-count: 1;
transform-origin: 50% 50%;
-webkit-animation: animationFrames linear 3s;
-webkit-animation-iteration-count: 1;
-webkit-transform-origin: 50% 50%;
-moz-animation: animationFrames linear 3s;
-moz-animation-iteration-count: 1;
-moz-transform-origin: 50% 50%;
-o-animation: animationFrames linear 3s;
-o-animation-iteration-count: 1;
-o-transform-origin: 50% 50%;
-ms-animation: animationFrames linear 2s;
-ms-animation-iteration-count: 1;
-ms-transform-origin: 50% 50%;
}
#keyframes animationFrames{
0% {
transform: translate(100%,-20px) rotate(0deg) ;
}
10% {
transform: translate(90%,-30px) rotate(5deg) ;
}
20% {
transform: translate(80%,-40px) rotate(15deg) ;
}
30% {
transform: translate(70%,-50px) rotate(10deg) ;
}
40% {
transform: translate(60%,-60px) rotate(5deg) ;
}
50% {
transform: translate(50%,-70px) rotate(0deg) ;
}
60% {
transform: translate(40%,-60px) rotate(-5deg) ;
}
70% {
transform: translate(30%,-50px) rotate(-10deg) ;
}
80% {
transform: translate(20%,-40px) rotate(-15deg) ;
}
90% {
transform: translate(10%,-30px) rotate(-10deg) ;
}
100% {
transform: translate(0%,0px) rotate(0deg) ;
}
}

It seems like you're on the right track, and CSS animations should be perfect for the task you're solving. A few quick pointers:
You've made prefixed animation calls like -webkit-, -moz-, -o- and -ms-. However, you've not made any prefixed keyframes. This makes the first part wasted. If you want full browser compatibility you also need prefixed keyframes and prefixed transforms.
Like this:
#keyframes animationFrames{
0% {
transform: translate(100%,-20px) rotate(0deg) ;
}
100% {
transform: translate(100%,-20px) rotate(0deg) ;
}
}
#-webkit-keyframes animationFrames{
0% {
-webkit-transform: translate(100%,-20px) rotate(0deg) ;
}
100% {
-webkit-transform: translate(100%,-20px) rotate(0deg) ;
}
}
....
and so on.
The other part is more esthetic, but I suggest trying to work on one property at a time. Try drawing your animation in lines on a piece of paper first, figure out the axis and vectors that it's moving on and code one at a time. I'm afraid no-one on here can give you a finished piece of code, but with enough practice, I'm sure you will get the hang of animating.
Need your help developers,
I am using images as a menu. I just want when i click on image it rotate 360 degree and then another page is open.
i try this.
<style>
.image {
overflow: hidden;
transition-duration: 0.8s;
transition-property: transform;
}
.image:active {
-webkit-transform: rotate(360deg);
}
</style>
html:
<img class="image" src="img path">
in this code image rotation is depend on click time and i want user just click once image rotate 360 degree and the link page display.
but this is not i want.
I am using jqueryMobile and phonegap
thanks in advance.
You can put the link url in the image as a data attribute:
<img id="theimage" data-linkurl="#page2"src="http://makeameme.org/media/templates/120/grumpy_cat.jpg" alt="" />
Then when you handle the click event,
You add the animation class.
You add an animationEnd handler that fires when the animation is complete. Use one() instead of on() as you only want this handler to fire once.
In the animationEnd handler you remove the animation class (so you can add it again next time), get the url from the data-attribute, and then navigate to the page.
$("#theimage").on("click", function(){
$(this).addClass("imageRot").one('webkitAnimationEnd mozAnimationEnd oAnimationEnd msAnimationEnd animationend', function () {
$(this).removeClass("imageRot"); //remove anim class
var url = $(this).data('linkurl'); //get url from data-attribute
$( ":mobile-pagecontainer" ).pagecontainer( "change", url); //navigate to page
});
});
For the animation class I have used #cracker's spin animation (thanks cracker!):
.imageRot {
-webkit-animation:spin 2s ease-in-out;
-moz-animation:spin 2s ease-in-out;
animation:spin 2s ease-in-out;
}
#-moz-keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
}
#-webkit-keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
}
#keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
}
Here is a working DEMO
you need to try using
.image {
-webkit-animation:spin 4s ease-in-out; // No more infinite
-moz-animation:spin 4s linear;
animation:spin 4s linear;
}
#-moz-keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
}
#-webkit-keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
}
#keyframes spin {
100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); }
OR
#-webkit-keyframes rotate {
100% { -webkit-transform: rotate(360deg); }
}
.rotate {
-webkit-animation-name: rotate;
-webkit-animation-duration: 4.5s;
-webkit-animation-iteration-count: infinite;
-webkit-transition-timing-function: linear;
}
DEMO1
DEMO2
try it:
<style>
.image {
overflow: hidden;
-webkit-transition: transform 0.8s;
transition: transform 0.8s;
}
.image:active {
-webkit-transform: rotate(360deg);
transform: rotate(360deg);
}
</style>
You didn't include a webkit option (-webkit-*) in transition.
You didn't include a non-webkit option in transform.
because of that, no matter what browser you were using, something were missing (transform or transition), and therefore the code didn't work on any browser.
edit: I noticed it wasn't what you were asking for. I don't believe that it can be done with CSS only. If you want, you can do it with jQuery:
<script>
$(".image").click(function(){
$(this).addClass("clicked").delay(800).removeClass("clicked");
});
</script>
<style>
.image {
overflow: hidden;
-webkit-transition: transform 0.8s;
transition: transform 0.8s;
}
.image.clicked {
-webkit-transform: rotate(360deg);
transform: rotate(360deg);
}
</style>
HTML
<img src = "some_image.png" alt = "test" class = "rotative" />
CSS
.canRotate
{
-webkit-animation: FullRotation 3s ease-out;
-o-animation: FullRotation 3s ease-out;
-ms-animation: FullRotation 3s ease-out;
-moz-animation: FullRotation 3s ease-out;
animation: FullRotation 3s ease-out;
}
#-webkit-keyframes FullRotation
{
from { -webkit-transform: rotate(0deg); }
to { -webkit-transform: rotate(360deg); }
}
#-o-keyframes FullRotation
{
from { -o-transform: rotate(0deg); }
to { -o-transform: rotate(360deg); }
}
#-ms-keyframes FullRotation
{

to { -ms-transform: rotate(360deg); }
}
#-moz-keyframes FullRotation
{

to { -moz-transform: rotate(360deg); }
}
#keyframes FullRotation

this.style.className = "canRotate";
var that = this;
setTimeout(function(){

I am trying to work around this bug: http://code.google.com/p/chromium/issues/detail?id=20574 thinking of performing the transform, and then afterwards removing it while positioning the element in its end position via JavaScript.
I tried
document.getElementById('popover').style.setProperty("-webkit-transform", "translate3d(0,0,0)")
and
document.getElementById('popover').style.setProperty("-webkit-transform", "none")
None seem to have any effect.
If I remove the transforms and position the elements manually the fixed element does behave as it should.
Here are the transforms themselves:
#popover.open {
display: block;
position: relative;
-webkit-animation: openpopup 0.2s 1;
-webkit-animation-fill-mode: forwards;
}
#popover.closed {
-webkit-animation: closepopup 0.2s 1;
-webkit-animation-fill-mode: forwards;
}
#-webkit-keyframes openpopup {
from {
-webkit-transform: translate3d(0, 100%, 0);
}
to {
-webkit-transform: translate3d(0, 0%, 0);
}
}
#-webkit-keyframes closepopup {
from {
-webkit-transform: translate3d(0, 0%, 0);
}
to {
-webkit-transform: translate3d(0, 100%, 0);
}
}
Javascript had a different name for the css property you are trying to change. It's called WebkitTransform.
document.getElementById('popover').style.setProperty("WebkitTransform", "none"); Should work.
I'm going mad trying to get a spinner to appear. I've bound my heavy processing function to a button thus:
$(document).delegate("#clearread", "tap", onClearRead);
So on tap it calls this:
var onClearRead = function() {
setTimeout($.mobile.showPageLoadingMsg, 5);
// Civilised cleaning of saved status
var jStorIndex = $.jStorage.index();
for (var i = 0; i < jStorIndex.length; i++) {
if( jStorIndex[i] != "version" ) {
$.jStorage.deleteKey(jStorIndex[i]);
}
}
// Load articles afresh
loadArticles();
$.mobile.changePage("#choosearticle");
} //onClearRead
I find that the spinner does not appear during the clearing/loading of articles (about 10 secs) but only for a brief period while the #choosearticle page loads (0.5 secs).
What am I doing wrong?
I have the spinner working elsewhere in the app.
Thanks
Try this:
$(document).delegate("#clearread", "tap", onClearRead);
var onClearRead = function() {
$.mobile.showPageLoadingMsg();
setTimeout(function(){
//Your heavy processing
$.mobile.changePage("#choosearticle");
}, 5);
} //onClearRead
jQuery.show( [duration ] [, complete ] )
Putting the heavy processing in the "complete" function slot, ensures the object (with show called on it) is visible before the show happens.
