Stop an animated SVG to a certain position on screen - css

Question

Using this example, is there a way to stop this CSS animation to a fixed point on the screen? So for instance, it's moving across and I decide to have it stop like 20px from the top right of the screen. Is this possible with just CSS?
.bird {
background-image: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/174479/bird-cells.svg);
background-size: auto 100%;
width: 88px;
height: 125px;
will-change: background-position;
animation-name: fly-cycle;
animation-timing-function: steps(10);
animation-iteration-count: infinite;
}
.bird--one {
animation-duration: 1s;
animation-delay: -0.5s;
}
.bird-container {
position: absolute;
top: 20%;
left: -10%;
transform: scale(0) translateX(-10vw);
will-change: transform;
animation-name: fly-right-one;
animation-timing-function: linear;
animation-iteration-count: infinite;
}
.bird-container--one {
animation-duration: 15s;
animation-delay: 0;
}
#keyframes fly-cycle {
100% {
background-position: -900px 0;
}
}
#keyframes fly-right-one {
0% {
transform: scale(0.3) translateX(-10vw);
}
10% {
transform: translateY(2vh) translateX(10vw) scale(0.4);
}
20% {
transform: translateY(0vh) translateX(30vw) scale(0.5);
}
30% {
transform: translateY(4vh) translateX(50vw) scale(0.6);
}
40% {
transform: translateY(2vh) translateX(70vw) scale(0.6);
}
50% {
transform: translateY(0vh) translateX(90vw) scale(0.6);
}
60% {
transform: translateY(0vh) translateX(110vw) scale(0.6);
}
100% {
transform: translateY(0vh) translateX(110vw) scale(0.6);
}
}
<div style="width:100%;">
<div class="bird-container bird-container--one">
<div class="bird bird--one"></div>
</div>
</div>

Answer 1

By changing the VW to a lower number, you can get it to stop a certain distance from the right side of the screen. If you always want the bird to stop when it's travelled approximately 90% of the screen width then you can change the VW to 90.
With the way it's currently setup, it's not easy to make it stop at a certain amount of pixels.
By setting your code like below at 50% and removing the higher percentages, you can get the bird to fly 90% to the right and fly up to the upper right corner.
50% {
transform: translateY(-20vh) translateX(90vw) scale(0.6);
}
