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


Refer to the documentation for <time> and <percentage> for details of the individual syntaxes allowed by this type.

Use in calc()

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