Superscript and Subscript

In HTML, text formatting plays a significant role. It helps to enhance the readability and presentation of web pages. In this tutorial, we will focus on two particular types of text formatting: Superscript and Subscript.

Superscript and subscript text are often used in scientific contexts, mathematical equations, footnotes, and more. They are essentially smaller lines of text that are positioned either slightly above the normal typographic baseline (superscript) or slightly below it (subscript).

Superscript Text in HTML​

To create superscript text in HTML, the <sup> tag is used. Here is the basic syntax:

<sup>Text</sup>

Here's an example of how you might use this in a real-world context:

<p>This is an example of <sup>superscript</sup> text.</p>

In the above example, the word "superscript" will appear slightly above the baseline compared to the rest of the sentence.

Subscript Text in HTML​

The subscript text in HTML is created using the <sub> tag. Here is the basic syntax:

<sub>Text</sub>

Here's an example of how you might use this in practice:

<p>This is an example of <sub>subscript</sub> text.</p>

In this example, the word "subscript" will appear slightly below the baseline compared to the rest of the sentence.

Using Superscript and Subscript in Mathematical Contexts​

Superscript and subscript are often used in mathematical equations. Here's an example of how you could represent H2O (Water) and E=mc^2 (Einstein's Theory of Relativity) using subscript and superscript respectively:

<p>H<sub>2</sub>O is the chemical formula for water.</p>
<p>E=mc<sup>2</sup> is Einstein's Theory of Relativity.</p>

In the first example, the '2' in 'H2O' appears as a subscript, and in the second example, '2' in 'E=mc^2' is displayed as a superscript.

Now you know how to create superscript and subscript text in HTML. It's a simple but powerful formatting tool that can enhance the readability and presentation of your web pages. Keep practicing and experimenting with these tags, and you'll soon master the art of HTML formatting. Happy coding!
