HTML - <sup> Tag

The HTML <sup> tag defines inline content that should be rendered as superscript. Superscripts are usually rendered with a raised baseline using smaller text.

The <sup> tag should be used only for typographical reasons that is, to adjust the position of the text to comply with typographical rules or standards rather than for presentation or appearance.

This <sup> tag is used for displaying exponents, such as "x3" and representing ordinal numbers, such as "4th".

Syntax

Following is the syntax of <sup> tag −

<sup>.....</sup>

Example

In the following example, we are creating an HTML document and using the <sup> tag to display text in superscript forms, as follows − 

<!DOCTYPE html>
<html>
<body>
   <h1>The sup tag</h1>
   <p> This is normal para </p>
   <p> this is <sup> superscript </sup> para </p>
</body>
</html>

When we run the above code, it will generate an output consisting of the text on the webpage.

Example

Considering the following example, we are using the <sup> tag to create an exponent, or power of a number. Both are the most common uses of superscripted text.

<!DOCTYPE html>
<html>
<body>
   <p> 
      One of the most common equations in all of physics is <var>E</var>= <var>m</var> <var>c</var> <sup>2</sup>.
   </p>
   <p> 
      Formula of (a + b ) <sup>2</sup> = a <sup>2</sup> + b <sup>2</sup> + 2*a*b 
   </p>
</body>
</html>

On running the above code, the output window will pop up displaying the text on the webpage.

Example

Following is the example, where we are going to use the <sup> tag to creating ordinal numbers such as "fourth" in English or "Quinto" in Spanish.

<!DOCTYPE html>
<html>
<body>
   <p> 
      The ordinal number "fifth" can be abbreviated in various languages as follows − 
   </p>
   <ul>
      <li>English: 5 <sup>th</sup></li>
      <li>French: 5 <sup>ème</sup></li>
   </ul>
</body>
</html>

When we run the above code, it will generate an output consisting of the text on the webpage.
