Clip path circle small gap issue - css

I have a page transition but when going from a white page to a black page, the circle clip path creates a small gap, as seen on the screenshot.
Meanwhile here is a demo https://elk-sand.vercel.app/. It happens when going from the home page to transformeren page from the navigation.
Another demo: https://codesandbox.io/s/dazzling-dirac-r000oy?file=/src/App.js
screenshot issue:
Funny how this question is being closed for not providing code while their is a code sandbox, so here you go for the ones who prefer it here:
.App {
font-family: sans-serif;
text-align: center;
}
#keyframes mymove {
from {
clip-path: circle(0%);
}
to {
clip-path: circle(50%);
}
}
<div
style="
height: 100vh;
background: red;
position: fixed;
inset: 0px;
animation: mymove 20s infinite;
"
className="App"
>
<div
style="
position: fixed;
inset: 0px;
background: yellow;
animation: mymove 20s infinite;
"
></div>
</div>
The issue is a red border around the yellow circle, which should not be there.

After some investigating, I found out it was due to a small scale from 105% to 100% and the clip-path circle which was getting bigger.
Adding translate-z did not solve this issue, unfortunately. I removed the small scale since it didn't add that much effect.
To fix the example that I sent is easy to solve just add 1% to the highest element circle path or set a delay on the first element.
.App {
font-family: sans-serif;
text-align: center;
}
#keyframes mymove {
from {
clip-path: circle(0%);
}
to {
clip-path: circle(50%);
}
}
<div
style="
height: 100vh;
background: red;
position: fixed;
inset: 0px;
animation: mymove 20s infinite;
animation-delay: 0.05s;
"
className="App"

<div
style="
position: fixed;

background: yellow;
animation: mymove 20s infinite;
"

Multiple Linear Animations On Same Line - Issue where second animation is not starting at the beginning

I'm working on a project where I want to have two animation with one following the other after a delay. I've gotten the two animation on the same line with one following after a delay, but I can't seem to get it work perfectly. The issue that I am having is that the first animation is starting after 0%/0vw, so it's show the animation start instead of it coming from off the page. I would really appreciate any help or advice on how to get this to work. Thank you!
.announcement {
justify-content: right;
align-items: center;
display: flex;
}
.announce {
font-size: 1.3rem;
position: relative;
/* animation: mymove 20s infinite;*/
/* animation-timing-function: linear;*/
animation: linear 15s mymove infinite;
}
.announce2 {
font-size: 1.3rem;
position: relative;
/* animation: mymove 20s infinite;*/
/* animation-timing-function: linear;*/
animation: linear 15s mymove2 infinite;
animation-delay: 5s;
}
#keyframes mymove {
from {right: 0vw;}
50% {right: 50vw !important;} /* ignored */
to {right: 100vw;}
}
#keyframes mymove2 {
from {right: 0vw;}
50% {right: 50vw !important;} /* ignored */
to {right: 100vw;}
}
<div class="announcement">
<div class="announce">
Hello
</div>
<div class="announce2">
Hello
</div>
</div>
To get the announcement off the screen to the right it needs to not only be positioned right: 0 but also to move further to the right by its own width. This can be achieved with a translation of 100%.
As an example, this snippet gives both announcements the same animation and other settings - apart from giving announement2 the animation delay.
The parent element has overflow hidden, and the body is given margin 0 to ensure that the announcements go fully from the right to the left.
body {
margin: 0;
}
.announcement {
justify-content: right;
align-items: center;
display: flex;
overflow: hidden;
}
.announce,
.announce2 {
font-size: 1.3rem;
position: relative;
animation: linear 15s mymove infinite;
right: 0;
transform: translateX(100%);
}
.announce2 {
animation-delay: 5s;
}
#keyframes mymove {
to {
right: 100vw;
transform: translateX(0%);
}
}
<div class="announcement">
<div class="announce">
Hello
</div>
<div class="announce2">
Hello
</div>
</div>
Note: if what you are wanting is an evenly spaced continuous flow then you might like to search for 'marquee' on StackOverflow - not the HTML tag which is deprecated but continuous rotating banner.

CSS Transition : large div disappears completely while animating

I have some problems with a CSS transition effect. I don't understand why, but it isn't working. Here is a demo that isn't working :
https://codyhouse.co/demo/ink-transition-effect/index.html
Here is an article about how this effect was done (before, when it did work) :
https://codyhouse.co/gem/ink-transition-effect
The code I'm working on to debug is this one :
https://codepen.io/1019/pen/YzxzNGX
HTML file :
<body>
CSS ANIMATIONS TEST
<div class='cd-transition-layer'>
<div class="bg-layer"></div>
</div>
</body>
CSS file :
.cd-transition-layer {

z-index: 30;
height: 100%;
width: 100%;
}
.cd-transition-layer .bg-layer {

left: 50%;
top: 50%;
z-index: 15;
transform: translateY(-50%) translateX(-2%);

}
#keyframes cd-sprite {
0% {
transform: translateY(-50%) translateX(-2%)
}
100% {
transform: translateY(-50%) translateX(-98%)
}
}
Can you please help me find what is wrong ?
Thank you !
EDIT : Okay, weird : it seems the div just completely disappears during the animation before reappering. If I keep focus on the div in the inspector, it stays there. Is it because it's too long (2500% width) ?
Moving large divs
It seems that animating a large div over the screen very fast can cause a render/flicker in webkit based browsers.
If i have to guess, it's probably due to performance reasons, where the browser cuts off things thats are not in the viewport. when moving to the next frame, it will not have the pixels ready to be rendered, resulting in a flicker.
It becomes more apparent when you remove the steps(24) from the animation.
The div will slide over the screen, and at some point just stop being visible.
Using background-position instead
When animating, instead of moving a div over the screen, we can also opt to move only the background instead.
background: url("https://i.imgur.com/9uDdPAP.png") no-repeat;
background-size: 2500% 100%; /* Size is needed to stretch 1 frame to fit the div */
background-position: 0% 0%; /* we can start from frame 0 */
animation: cd-sprite 1s steps(24);
/* the animation is the same, we only move the background instead. (in 24 steps) */
#keyframes cd-sprite {
0% {
background-position: 0% 0%;
}
100% {
background-position: 100% 0%;
}
}
* {
box-sizing: border-box;
}
.cd-transition-layer {
position: fixed;
top: 0;
left: 0;
z-index: 30;

animation: cd-sprite 1s steps(24) infinite;
animation-direction: alternate;
animation-delay: 1s;
animation-fill-mode: forwards;
border: 36px solid red;
}
#keyframes cd-sprite {

100% {

CSS3 Animation: How do I create smooth movement of background image? Seems to be a Chrome only issue

Trying to smoothly animate a div's background image #bg2 over a short pixel distance (while a clip path animates over it). I'm not able to get the image to move smoothly, it jitters and judders. The clip path animation is fine.
I've tried different easing (linear / ease-in-out etc) suggested in another SO thread, and also extending the distance it needs to move, but it still seems to jump pixel by pixel (sort of), rather than move smoothly. (Although, extending the move distance isn't an option in the actual use case).
How can smooth movement of the cat background image #bg2 be accomplished? Thanks.
** Edit: It's totally smooth for me in Firefox, for me it's jittery in Chrome 91.0.4472.114 on Mojave 10.14.6, and less jittery in Safari. For other it seems to be smooth on Chrome also. Hmmm...

I'm a bit curious about why having a large banner while not displaying it all.
Anyways, I provide another way of animating, basically just changing the height. Hopefully that could give some ideas.
I removed the width to make it slightly more responsive.
The animation somewhat jittery in this solution, but I guess that it depends on your bezier curve. So perhaps that's the issue all along?
var clickTag = "#";
#main-container {
position: relative;

box-sizing: border-box;

top: 50%;

height: 40%;
aspect-ratio: 1;
border-radius: 50%;

Zoom background image with background size cover

I'm using this code to make a wordpress header picture slowly zoom in and out. It works in Chrome and Firefox, but in Safari it seems like the background-size: cover that is set for the picture overrides the zoom. Is there a way to zoom from cover to "150% cover"? Basically tell it to start as cover and then go 150% from there? This code wont even zoom at all in Safari, and background-size: 100% doesn't make the picture tall enough on mobile so I'd need a different solution.
Thank you!
#-webkit-keyframes animatedBackground {
from {
background-size: 100%;}
50% {
background-size: 150%; }
 to {
   background-size: 100%; }
}
.home .header-media .wrapper:before {
-webkit-animation: animatedBackground 90s linear infinite;
-moz-animation: animatedBackground 90s linear infinite;
animation: animatedBackground 90s linear infinite;
background-position: center;
background-size: cover;
}
Here is working snippet, transition and background-size do the trick.
.parent {
width: 400px;
height: 300px;
}
.child {
transition: all .5s;
width: 100%;
height: 100%;
background-color: black; /* fallback color */
background-image: url("https://upload.wikimedia.org/wikipedia/commons/b/b4/The_Sun_by_the_Atmospheric_Imaging_Assembly_of_NASA%27s_Solar_Dynamics_Observatory_-_20100819.jpg");
background-position: center;
background-size: 100%;
}
.parent:hover .child,
.parent:focus .child {
background-size: 150%;
}
<div class="parent">
<div class="child"></div>

Animation-play-state not playing nice with animation-delay in Safari

I am working on modifying this example in some ways for use in my application. This works awesome in Chrome and FF, but in Safari, not so much. If you look you will see in Chrome the pie charts look as expected, but in Safari they are all "whole".
The css (copied from the example) looks like this:
.pie {
display: inline-block;
position: relative;
width: 100px;
line-height: 100px;
border-radius: 50%;
background: yellowgreen;
background-image: linear-gradient(to right, transparent 50%, #655 0);
color: transparent;
text-align: center;
}
#keyframes spin {
to { transform: rotate(.5turn); }
}
#keyframes bg {
50% { background: #655; }
}
.pie::before {
content: '';
position: absolute;
top: 0; left: 50%;
width: 50%; height: 100%;
border-radius: 0 100% 100% 0 / 50%;
background-color: inherit;
transform-origin: left;
animation: spin 50s linear infinite, bg 100s step-end infinite;
animation-play-state: paused; <-- Safari's issue
animation-delay: inherit;
}
I noted the second-to-last line in the code to identify the problem. When animation-play-state is set to paused, Safari will not put the animation in the initial condition set by animation-delay. Chrome and FF seem to look at the animation-delay, put the animation in the state it would be at that delay, and then stay paused.
Is there a workaround I am missing where Safari will put the animation in the initial condition and then stay paused?
