The :out-of-range CSS pseudo-class matches when an element has its value attribute outside the specified range limitations for this element. It allows the page to give a feedback that the value currently defined using the element is outside the range limits. A value can be outside of a range if it is either smaller or larger than maximum and minimum set values.

Note: this pseudo-class only applies to elements that have a range limitations. In absence of such a limitation, the element can neither be 'in-range' nor 'out-of-range'.



<form action="" id="form1">
    <ul>Values between 1 and 10 are valid.
            <input id="value1" name="value1" type="number" placeholder="1 to 10" min="1" max="10" value="12">
            <label for="value1">Your value is </label>


li {
    list-style: none;
    margin-bottom: 1em;
input {
    border: 1px solid black;
input:in-range {
    background-color: rgba(0, 255, 0, 0.25);
input:out-of-range {
    background-color: rgba(255, 0, 0, 0.25);
    border: 2px solid red;
input:in-range + label::after {
    content:' OK';
input:out-of-range + label::after {
    content:'out of range!';
