I have 2 half-page-sized overlays that translate the opposite ways to give the illusion that the screen is opening up. In addition, I want them to stop at about 8% from the viewport top or bottom and not disappear entirely. It doesn't really work with % because on mobile devices with bars and other UI they are get cut off. I have tried to use vh but it just disappears into the viewport edges.

Your transform value for that should be translateY(42vh) (and -42vh) instead of +/-92vh, that's the amount the elements move up/down:

I'm trying to ensure that only the box shadow has the pulsate and not the whole button.
The experience should see the button solid but with the box shadow fading in and out if that makes sense.
Here is my code:
.gps_ring {
border: 3px solid #999;
-webkit-border-radius: 30px;
height: 42px;
width: 180px;
background-color: blue;
text-align: center;
display: block;
color: white;
box-shadow: 0 0 17px black;
-moz-box-shadow: 0 0 17px black;
-webkit-box-shadow: 0 0 17px black;
-webkit-animation: pulsate 1s ease-out;
-webkit-animation-iteration-count: infinite;
opacity: 0.0
}
#-webkit-keyframes pulsate {
0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
50% {opacity: 1.0;}
100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}
EXAMPLE
Simply animate only the shadow, like this
.gps_ring {
border: 3px solid #999;
border-radius: 30px;
height: 42px;
width: 180px;
background-color: blue;
text-align: center;
display: block;
color: white;
box-shadow: 0 0 17px black;
animation: pulsate 1s ease-out infinite;
}
#-webkit-keyframes pulsate {
0% { box-shadow: 0 0 0 black; }
50% { box-shadow: 0 0 17px black; }
100% { box-shadow: 0 0 0 black; }
}

Hope this would be a help.
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:

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.
Sadly, this is something that you will not be able to fix, amend or control with browsers. You will have to use some form of hack to get it to work or confuse the system into doing what you want, but from a normal render, it won't work.
What you could possibly do is add a delay to the animation.
-webkit-animation: pulsate 0.8s linear 10ms infinite;
-moz-animation: pulsate 0.8s linear 10ms infinite;
-o-animation: pulsate 0.8s linear 10ms infinite;
animation: pulsate 0.8s linear 10ms infinite;
JSFiddle Example
What this will do is let the page render, paint and display, then it will wait for 100ms (0.1s) before starting the animation.
If this doesn't work, then it's down to FF not rendering animations as cleanly as Chrome or some other browsers and that is simply a browser issue and will be exceedingly difficult to get round.
Every browser has a completely different tree, render and paint process for displaying HTML & CSS to your monitor. Gecko (FF) and WebKit (Chrome) both use completely different methods and processes to display the page and sadly, when it comes to doing animations, Gecko has the tiniest amount of lag when starting up the animation which is why you see the small bit of lag/jerkiness when the animation begins.
Webkit flow
Gecko flow
As you can see from the above flows, both flows are completely different and the way that the DOM is loaded in, rendered, painted and then displayed is completely different.
Hope this help clears up the issue.
I've added one of the best pieces of information for you to read up on about browser rendering. It's always good to have an understanding of how browsers work when working on the front-end.
How modern browsers work
I am using keyframes with box-shadow to create an animation. Then, I am using the animation command to select the keyframe name and define some detailes on the animation (duration, delay etc...).
#myanimation{
animation: x 1s 1 ease-out ;
-webkit-animation: x 1s 1 ;
-webkit-backface-visibility: hidden;
-moz-animation: x 1s 1;
-o-animation: x 1s 1 ;
}
I will not post my keyframe, because its long. However, even though my animation duration is only 1 seconds, I am experiencing lags.
I tried everything to fix the lags, I added linear,ease-in-out etc.. all kinds of tags to the animation commnad but unsuccessful.
At the end, I just
deactivated the add-ons
(since add-ons also reduce the performance of firefox especially add-ons that block add-ons). After deactivating all my add-ons, it worked perfectly.
For some reason when you animate with Skew(0.1deg) it is not choppy.
This is on firefox 91.0 (64bit).
