<angle> CSS type

Try it

transform: rotate(45deg);

transform: rotate(3.1416rad);

transform: rotate(-50grad);

transform: rotate(1.75turn);

<section class="default-example" id="default-example">
  <div class="transition-all" id="example-element">
    This box can rotate to different angles.
  </div>
</section>

#example-element {
  background-color: #0118f3;
  padding: 0.75em;
  width: 180px;
  height: 120px;
  color: white;
}

Syntax

The <angle> data type consists of a <number> followed by one of the units listed below. As with all dimensions, there is no space between the unit literal and the number. While some legacy uses accept a unitless 0, you should always include a unit for zero values, such as: 0deg, 0grad, 0rad, or 0turn.

Optionally, it may be preceded by a single + or - sign. Positive numbers represent clockwise angles, while negative numbers represent counterclockwise angles. For static properties of a given unit, any angle can be represented by various equivalent values. For example, 90deg equals -270deg, and 1turn equals 4turn. For dynamic properties, like when applying an animation or transition, the effect will nevertheless be different.

Units

deg

Represents an angle in degrees. One full circle is 360deg. Examples: 0deg, 90deg, 14.23deg.

grad

Represents an angle in gradians. One full circle is 400grad. Examples: 0grad, 100grad, 38.8grad.

rad

Represents an angle in radians. One full circle is 2 radians which approximates to 6.2832rad. 1rad is 180/ degrees. Examples: 0rad, 1.0708rad, 6.2832rad.

turn

Represents an angle in a number of turns. One full circle is 1turn. Examples: 0turn, 0.25turn, 1.2turn.

Examples

Setting a clockwise right angle

[A diagram showing a clockwise 90-degree rotation along a circle by moving from the topmost point to the rightmost point.]

90deg = 100grad = 0.25turn 1.5708rad

Setting a flat angle

[A diagram showing a clockwise 180-degree rotation along a circle by moving from the topmost point to the bottommost point.]

180deg = 200grad = 0.5turn 3.1416rad

Setting a counterclockwise right angle

[A diagram showing a counterclockwise 90-degree rotation along a circle by moving from the topmost point to the leftmost point.]

-90deg = -100grad = -0.25turn -1.5708rad

Setting a null angle

[A diagram showing a 0-degree rotation. There is no movement.]

0deg = 0grad = 0turn = 0rad
