</div>About this button
A dark keycap-style Add to cart button in a frosted frame with a soft rainbow glow behind it. Pressing squashes the button and tightens the glow.
How it works
A frosted frame with a backdrop-filter surrounds a dark keycap button made of two stacked gradients. A blurred conic gradient behind it gives the rainbow glow, and active states scale the button and shrink the blur so it looks pressed. The inner span is a second rounded plate.
Ways to customise it
- Edit the colours of the conic gradient.
- Change the 50px font size.
- Change the label text.
Good to know
It is a real button. The glow only animates in browsers that support registered custom properties, otherwise it stays still and still looks good. The monospace font falls back to the system one.
