The radial-gradient function takes its start from a single point in the center and smoothly spreads outward in a circular or elliptical (by default) shape.

The basic syntax includes the radial-gradient function and the following arguments:

• Shape — circle or ellipse.
• Position, which you can define with length (px, pt, cm), percentage (%), or predefined text values (left, bottom, right, top, etc.)
• Size, which is set by default as farthest-side, can also take values like closest-side, closest-corner, or farthest-corner.
