PostCSS Conic Gradient

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/svg+xml,...");
    background-image: conic-gradient(red, yellow, lime, aqua, blue, magenta, red);
}
