`:out-of-range` CSS pseudo-class

The :out-of-range CSS pseudo-class represents an <input> element whose current value is outside the range limits specified by the min and max attributes.

label {
  display: block;
  margin-top: 1em;
}

input:out-of-range {
  background-color: orangered;
}

<form>
  <label for="amount">How many tickets? (You can buy 2-6 tickets)</label>
  <input id="amount" name="amount" type="number" min="2" max="6" value="4" />

  <label for="dep">Departure Date: (Whole year 2022 is acceptable)</label>
  <input
    id="dep"
    name="dep"
    type="date"
    min="2022-01-01"
    max="2022-12-31"
    value="2025-05-05" />

  <label for="ret">Return Date: (Whole year 2022 is acceptable)</label>
  <input id="ret" name="ret" type="date" min="2022-01-01" max="2022-12-31" />
</form>

This pseudo-class is useful for giving the user a visual indication that a field’s current value is outside the permitted limits.

[!NOTE] This pseudo-class only applies to elements that have (and can take) a range limitation. In the absence of such a limitation, the element can neither be “in-range” nor “out-of-range.”

Syntax

:out-of-range {
  /* ... */
}
