I am trying to show a CSS3 animation as a loader-animation when I navigate to one of my subpages. I am using keyframe animation on rotateY. The issue is that on Firefox, while navigation to another page, the animation does work, but its very jerky and choppy.
While on Chrome and Safari, the same animation works smoothly and perfectly.
Here is a fiddle: http://jsfiddle.net/p6mgxpbo/
HTML:
<div class="gb-loading">
<div id="animatedElem" class="pin-c">
<div class='pin'></div>
</div>
<div class="pin-mirror"></div>
<div id="gb-lb" class="load-bounce"></div>
</div>
CSS:
.gb-loading {
position: fixed;
left: 0;
right: 0;
top: 50%;
bottom: 0;
width: 70px;
height: 70px;
margin: auto;
z-index: 101;
margin-top: -100px;
}
.pin-c {
width: 70px;
height: 70px;
position: absolute;
top: 0;
left: 0;
z-index: 11;
-webkit-animation: pulsate 1.5s linear infinite;
-moz-animation: pulsate 1.5s linear infinite;
-o-animation: pulsate 1.5s linear infinite;
animation: pulsate 1.5s linear infinite;
}
.pin {
width: 70px;
height: 70px;
background-color: #34baab;
position: absolute;

top: 0;
-webkit-border-radius: 50% 50% 50% 0;

-webkit-transform: rotate(-45deg);
-moz-transform: rotate(-45deg);

}
.pin-mirror {

-o-transform: rotate(-45deg);

}
.pin:after {
content: '';
width: 25px;
height: 25px;
margin: 22px 0 0 22px;
background-color: #003146;

}
.load-bounce {

height: 25px;

left: 65px;
background-color: #003146;
-webkit-transform: translateZ(0.5);
-moz-transform: translateZ(0.5);

-webkit-border-radius: 50%;
border-radius: 50%;
-webkit-animation: bounce .5s linear infinite alternate;
-moz-animation: bounce .5s linear infinite alternate;
-o-animation: bounce .5s linear infinite alternate;
animation: bounce .5s linear infinite alternate;
}
@-webkit-keyframes pulsate {
0% {
-webkit-transform: rotateY(0deg);
}
100% {
-webkit-transform: rotateY(360deg);
}
}
@-moz-keyframes pulsate {
0% {
-moz-transform: rotateY(0deg);
}
100% {
-moz-transform: rotateY(360deg);
}
}
@keyframes pulsate {
0% {
transform: rotateY(0deg);
}
100% {
transform: rotateY(360deg);
}
}
@-webkit-keyframes bounce {
0% {
-webkit-transform: translateY(-10px);
}
100% {
-webkit-transform: translateY(-40px);
}
}
@keyframes bounce {
0% {
transform: translateY(-10px);
}
100% {
transform: translateY(-40px);
}
}
@-moz-keyframes bounce {
0% {
-moz-transform: translateY(-10px);
}
100% {
-moz-transform: translateY(-40px);
}
}
The jerk only comes when Its there on a page which is loading other resources. I am trying to use this element as a pre-loading animation. So it's on the page until the rest of the page is loading. I also have google maps on the same page. So, while the browser is downloading other resources, till that time the animation jerks. You'll not be able to see the jerk on the fiddle.
Need some insights on how to fix this. Thanks in advance !!
P.S: I did go through a lot of answers related to this on StackOverflow and tried searching on Google, but to no avail.
