        *
    </form>

Required

In order to make this textbox mandatory, we can use required attribute.

<body>
    <form>
        <input type="text" id="myName" name="myName" required placeholder="Please enter your name" />*
    </form>
</body>

Note that required attribute value is optional in HTML 5, we can just write required or required="required". Functionally both are same.
