The :required CSS pseudo-class represents any <input> , <select> , or <textarea> element that has the required attribute set on it. This pseudo-class is useful for highlighting fields that must have valid data before a form can be submitted. Note: The :optional pseudo-class selects optional form fields.

The required attribute is a boolean attribute. When present, it specifies that an input field must be filled out before submitting the form. Note: The required attribute works with the following input types: text, search, url, tel, email, password, date pickers, number, checkbox, radio, and file.

When including the required attribute, provide a visible indication near the control informing the user that the <input> , <select> or <textarea> is required. In addition, target required form controls with the :required pseudo-class, styling them in a way to indicate they are required.
