:in-range

Summary

The :in-range CSS pseudo-class matches when an element has its value attribute inside the specified range limitations for this element. It allows the page to give a feedback that the value currently defined using the element is inside the range limits.

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'.

            <label for="value1">Your value is </label>
