Kitty reflected on an ancient blog post here on CSS-Tricks on how to make an animated pie timer. The old technique is still clever. The new technique is equally clever and much easier. I particularly like the steps() animation function that “flips” the “mask” from side-to-side by rotating a pseudo-element half a turn, That’s just good CSS trickery by gosh.
Allow me to do the “CSS Pie Timer Re-Revisted” post a year or two early just to get ahead of things. It’s not a trick anymore — we just use a conic-gradient() and animate the percentage value as a custom property 0% to 100%.
@property --percentage {
initial-value: 0%;
inherits: false;
syntax: '<percentage>';
}
.chart {
background: conic-gradient(red var(--percentage), white 0);
animation: timer 4s infinite linear;
}
@keyframes timer {
to {
--percentage: 100%;
}
}This should work in Chrome (but nothing else) for now:
