When i was a little kid, I was really scared of the dark. But then I came to understand, dark just means the absence of photons in the visible wavelength -- 400 to 700 nanometers. Then i thought, well, its really silly to be afraid of a lack of photons. Then i wasn't afraid of the dark anymore after that.

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>.
