CSS Conic gradients are a new type of gradient introduced in the CSS Images and Replaced Content specification which is currently in a working draft state. Conic gradients are similar to radial gradients which gradually change color from a central location. However, Conic gradients change color around a central location.
Note: At the time of posting, there is little current browser support for conic gradients (Can I Use browser support). Chrome 69 supports conic gradients and webkit is currently developing it.
