PostCSS Conic Gradient is a PostCSS plugin that allows you to use conic gradients in your CSS files. It is based on Lea Verou’s excellent conic-gradient polyfill.

Conic gradients are awesome, but browsers haven’t realized yet. This polyfill lets you experiment with them now. If you like them, ask browser vendors to implement them!

/* before */
.hue-wheel {
	background-image: conic-gradient(red, yellow, lime, aqua, blue, magenta, red);
}
/* after */
.hue-wheel {
	background-image: url("data:image/png;base64,...");
	background-image: conic-gradient(red, yellow, lime, aqua, blue, magenta, red);
}
