I believe that in order to better your knowledge base, it takes a lot of failing in order to succeed. I don't consider anything a failure as long as you get back up and you learn from your own mistakes.

conic-gradient()

The conic-gradient() CSS function creates an image consisting of a gradient with color transitions rotated around a center point (rather than radiating from the center). Example conic gradients include pie charts and color wheels. The result of the conic-gradient() function is an object of the <gradient> data type, which is a special kind of <image>.
