<angle-percentage>

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The <angle-percentage> CSS data type represents a value that can be either a <angle> or a <percentage>.

Where an <angle-percentage> is specified as an allowable type, this means that the percentage resolves to an angle and therefore can be used in a calc() expression.
