HTML <sup> Tag

The <sup> tag is used in HTML to define superscript text. Superscript text appears half a character above the normal line of text. It is commonly used for mathematical exponents, footnotes, and annotations.

Here is an example of how the <sup> tag is used:

<p>2<sup>3</sup></p>

Output:

2³

In the example above, the number 3 is displayed as a superscript, indicating that it is an exponent of the number 2.

Main Attributes of the <sup> Tag

Attribute	Description
style	Specifies CSS styles to be applied to the superscript text
class	Specifies one or more class names for the element (referring to a class in a CSS stylesheet)

Here is an example of how the <sup> tag can be used with the style attribute:

<p>E=mc<sup style="font-size: 10px;">2</sup></p>

Output:

E=mc²

In the example above, the number 2 is displayed as a superscript with a smaller font size.

Remember to always use the <sup> tag for indicating elements that should be displayed as superscript in your HTML document.
