SVG Line Animation Reversed in Safari? - css

Question

I've built pretty simple spinning animations for a site, and they look great in Chrome/Firefox, but for some reason, they're animating in reverse in Safari. I've played around with changing values of the offsets, but nothing seems to be working. Is there a workaround for this at all?
.sq {
width: 50vw;
height: auto;
padding: 2.2vw;
}
.path {
stroke-dasharray: 250;
stroke-dashoffset: 250;
animation: line 3s ease forwards;
}
#keyframes line {
from {
stroke-dashoffset: -250;
}
to {
stroke-dashoffset: 0;
}
}
<div class="sq">
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 81.32 81.32">
<defs>
<style>
.cls-1{fill:#202020;opacity:0.1;}
.path{fill:none;stroke:#ef3f44;stroke-miterlimit:10;stroke-width:5px;}
</style>
</defs>
<g id="94" data-name="94">
<g id="Objects">
<circle cx="40.66" cy="40.66" r="27.17" class="cls-1"/>
<path d="M40.66 79.15a38.49 38.49 0 1 1 38.49-38.49 38.53 38.53 0 0 1-38.49 38.49zm0-76.07a37.58 37.58 0 1 0 37.58 37.58A37.63 37.63 0 0 0 40.66 3.08z" class="cls-1"/>
<path d="M26.83 5.1a38.16 38.16 0 1 0 13.83-2.6" class="path"/>
</g>
</g>
</svg>
</div>

Answer 1

In order not to use negative values of stroke-dashoffset, you can use double the positive value of stroke-dashoffset: 500;
Instead of negative values
#keyframes line {
from {
stroke-dashoffset: -250;
}
to {
stroke-dashoffset: 0;
}
}
Use double positive values:
#keyframes line {
from {
stroke-dashoffset: 250;
}
to {
stroke-dashoffset: 500;
}
}
.sq {
width: 50vw;
height: auto;
padding: 2.2vw;
}
.path {
stroke-dasharray: 250;
stroke-dashoffset: 250;
animation: line 3s ease forwards;
}
#keyframes line {
from {
stroke-dashoffset: 250;
}
to {
stroke-dashoffset: 500;
}
}
<div class="sq">
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 81.32 81.32">
<defs>
<style>
.cls-1{fill:#202020;opacity:0.1;}
.path{fill:none;stroke:#ef3f44;stroke-miterlimit:10;stroke-width:5px;}
</style>
</defs>
<g id="94" data-name="94">
<g id="Objects">
<circle cx="40.66" cy="40.66" r="27.17" class="cls-1"/>
<path d="M40.66 79.15a38.49 38.49 0 1 1 38.49-38.49 38.53 38.53 0 0 1-38.49 38.49zm0-76.07a37.58 37.58 0 1 0 37.58 37.58A37.63 37.63 0 0 0 40.66 3.08z" class="cls-1"/>
<path d="M26.83 5.1a38.16 38.16 0 1 0 13.83-2.6" class="path"/>
</g>
</g>

</div>

Answer 2

Safari doesn't support negative dashoffsets. You'll need to work around that by reversing your path and having the dashoffset animate the other way.

Answer 3

Had the same issue for an svg circle. I wanted the animation to progress counter clockwise. Ended up solving it by horizontally flipping the circle and using a positive dash offset.
I used a transform to flip the circle.
scale(-1 1)
