To mark superscripted text in HTML, use the <sup>…</sup> tag. Just keep in mind both the opening and closing tag is mandatory while using the <sup>...</sup> tag.
The superscript text appears to be half a character above the normal line. It is displayed as a smaller font.
You can try the following code to mark superscripted text in HTML. Here, we are writing the value 2 4 using the <sup> tag,
<!DOCTYPE html> <html> <head> <title>HTML text superscript</title> </head> <body> <h1>Heading</h1> <p> Value: 2 <sup>4</sup> = 16 </p> </body> </html>
Output
