ValidityState: rangeOverflow property
rangeOverflow property of a
ValidityState object indicates if the value of an
<input>, after having been edited by the user, does not conform to the constraints set by the element's
If the field is numeric in nature, including the date, month, week, time, datetime-local, number and range types and a
max value is set, if the value doesn't conform to the constraints set by the
max value, the
rangeOverflow property will be true.
Given the following:
<input type="number" min="20" max="40" step="2" />
value > 40,
rangeOverflow will be true. When
true, the element matches the
:out-of-range CSS pseudo-classes.
