<time-percentage>

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

Syntax

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

Formal syntax

<time-percentage> = 
  <time>        |
  <percentage>

Examples

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.

Valid percentages

50%
+50%        Optional plus sign
-50%        Negative percentages are not valid for all properties that accept percentages

Invalid percentages

50 %        Space not allowed between the number and the percentage sign

Valid times

12s         Positive integer
-456ms      Negative integer
4.3ms       Non-integer
14mS        The unit is case-insensitive, although capital letters are not recommended.
+0s         Zero with a leading + and a unit
-0ms        Zero with a leading - and a unit

Invalid times

0           Although unitless zero is allowed for <length>s, it's invalid for <time>s.
12.0        This is a <number>, not a <time>, because it's missing a unit.
7 ms        No space is allowed between the number and the unit.
