Maxlength and Minlength Attributes
When the maxlength and minlength attributes are used together on an <input> element. In this case, the value of the maxlength attribute must be equal to or greater than the value of the minlength attribute.
The maxlength attribute controls the maximum length of the <input> element's value.
The minlength attribute is used to control the minimum value of the <input> element.
