Web/CSS/angle

The <angle> CSS data type represents an angle value expressed in degrees, gradians, radians, or turns. It is used, for example, in <gradient>s and in some transform functions.

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. The angle unit is optional after the number 0.

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 2π radians which approximates to 6.2832rad. 1rad is 180/π 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

90deg = 100grad = 0.25turn ≈ 1.5708rad

Setting a flat angle

180deg = 200grad = 0.5turn ≈ 3.1416rad

Setting a counterclockwise right angle

[[File:../../../../../media.prod.mdn.mozit.cloud/attachments/2012/07/09/3408/3c7c819fc7e98e06177581e34150248a/AngleMinus90.png|class=default internal|AngleMinus90.png]]

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

Setting a null angle

0 = 0deg = 0grad = 0turn = 0rad
