  • Last Updated : 01 Jul, 2021

The superscript object in HTML DOM is used to represent the HTML <sup> element. The superscript element can be accessed by using getElementById().
Syntax: 
 

document.getElementById("id") 

Where id is assigned to the <sup> tag.
Example :

        <script>
            function Geeks() {
                var txt = document.getElementById("sup_scr");
                txt.style.color = "green";
            }
