CSS "d" path - attribute doesn't work in Safari, FireFox - css

Question

I want use CSS animation for attribute "d" to SVG path.
This example working in Google chrome:
body {
background-color: #022040;
}
#path {
d: path('M425,225 L475,275 L575,175 L675,275 L775,175 L875,275 L925,225');
stroke: #1EFE64;
fill: none;
animation-name: path;
animation-duration: 5s;
animation-timing-function: ease-in;
animation-fill-mode: forwards;
}
#keyframes path {
0% {
d: path('M425,225 L475,275');
}
25% {
d: path('M425,225 L475,275 L575,175 L575,175 L575,175 L575,175 L575,175');
}
50% {
d: path('M425,225 L475,275 L575,175 L675,275 L675,275 L675,275 L675,275');
}
75% {
d: path('M425,225 L475,275 L575,175 L675,275 L775,175 L775,175 L775,175');
}
90% {
d: path('M425,225 L475,275 L575,175 L675,275 L775,175 L875,275 L875,275');
}
100% {
d: path('M425,225 L475,275 L575,175 L675,275 L775,175 L875,275 L925,225');
}
}
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="1000" height="400">
<path id="path" stroke-width="20"/>
</svg>
But doesn't work in Safari Pc/Mobile and FireFox.
How to fix the bug?
Or should I use the tag "animate" in svg?
Help me please)
Thank you!

Answer 1

d is an SVG “Geometry Property” defined in the SVG 2 specification at https://svgwg.org/svg2-draft/paths.html#TheDProperty. Google Chrome’s Blink layout engine is the only layout engine to support this property and its implementation doesn’t match the current specification definition.

And, yes, you can achieve the same effect using the SVG animate element:
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 1000 1000">
<title>Path Animation</title>
<path fill="none" stroke="hsl(139, 99%, 56%)" stroke-width="20">
<animate attributeName="d" values="
M 425 225 L 475 275;
M 425 225 L 475 275 L 575 175 L 575 175 L 575 175 L 575 175 L 575 175;
M 425 225 L 475 275 L 575 175 L 675 275 L 675 275 L 675 275 L 675 275;
M 425 225 L 475 275 L 575 175 L 675 275 L 775 175 L 775 175 L 775 175;
M 425 225 L 475 275 L 575 175 L 675 275 L 775 175 L 875 275 L 875 275;
M 425 225 L 475 275 L 575 175 L 675 275 L 775 175 L 875 275 L 925 225
" keyTimes="0; 0.25; 0.5; 0.75; 0.9; 1" calcMode="spline" keySplines="0.42 0 1 1; 0.42 0 1 1; 0.42 0 1 1; 0.42 0 1 1; 0.42 0 1 1" dur="5s" fill="freeze"/>
</path>
</svg>
0.42 0 1 1 is the set of cubic Bézier values for the ease-in animation-timing-function property keyword as defined in the CSS Timing Functions, Level 1 specification: https://drafts.csswg.org/css-timing-1/#valdef-cubic-bezier-timing-function-ease-in.
