CSS Sunrise

This is another CSS art that I make for this challenge. I use the position again to manipulate location of element to center the sun and hide the lower half of the sun. But in this CSS art I use radial-gradient to simulate the lighting.

Radial gradient is the CSS property that use to setup the gradient in ellipse radial. You need to specify the center of the gradient and colors to stop. I don't have much content to explain as the MDN documentation is probably do this better.
