HTML - Tag

HTML  tag defines inline content that should be rendered as superscript. Superscripts are usually rendered with a raised baseline using smaller text. HTML tag is used for displaying exponents, such as "x³" and representing ordinal numbers, such as "4^th".

The 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.

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

Exponent element using sup tag

Considering the following example, we are using the 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>
</body>
</html>

Ordinal numbers using sup tag

Following is the example, where we are going to use the 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
