.element { animation-range: cover; }
.element { corner-shape: superellipse(2); }
.element { corner-shape: scoop; }
.element { rotate: asin(-0.5); }
.element { rotate: acos(0.5) }
::picker-icon { content: "✓"; }
::scroll-marker:target-after { background: red; }
.element { transform: translateY(calc(sin(20deg * var(--i)) * 100px)); }
.element { transform: translateY(calc(cos(20deg * var(--i)) * 100px)); }
.element { transform: translateY(calc(tan(15deg * var(--i)) * 5dvh)); }
.element { background-image: cross-fade(url(a), url(b)); }
.element { background-image: image-set(url("image.png") 1x, url("image-large.png") 2x);
}
.triangle { clip-path: shape(from 50% 0%, line by 50% 100%, hline to 0%, line to 50% 0%, close); }
.element { background-image: paint(polka-dots); }
