HTML <sup> Tag

The HTML sup element is used to describe one or more superscript contents. The sup tag shows a text which is presented above the regular line and half the length of the character. And, this text is simply placed in a smaller font. We can also use the sup tag for representing the Mathematical formulas. Suppose, we want to write 10 to the power of 3, then we can write this using the tiny tag or the sup tag.

It is important to keep in mind that the sup element must be used to define superscript content in HTML documents.

Syntax:

<body>
<p> ……………..
<sup>…………… </sup>
……………. </p>
</body>
