The angle on CSS represents a certain angle value that can be expressed in degrees, gradians, radians, or turns. Angle value can be used for rotations, transformations or gradients, etc.

Syntax: The angle consists of a number followed by one of the allowed units.

property: number unit;

Allowed units:

deg: Represents an angle in degrees. One full circle is 360deg. Examples: 0deg, 90deg.
grad: Represents an angle in gradians. One full circle is 400grad. Examples: 0grad, 38.8grad.
rad: Represents an angle in radians. One full circle is 2π radians which approximate to 6.2832rad. 1rad is 180/π degrees. Examples: 0rad, 1.07rad.
turn: Represents an angle in a number of turns. One full circle is 1turn. Examples: 0turn, 1.2turn.

Example 1: using the deg unit to rotate an element by 90 degrees.
