Mastering HTML Subscript Text

Introduction

In HTML, the <sub> tag is used to specify inline text which should be displayed as the subscript for solely typographical reasons. The content inside this tag is typically rendered with a lowered baseline using smaller text. In this lab, you will learn how to use the <sub> tag in HTML to display subscripted text.

Add the HTML boilerplate

Create a new file called index.html.

Add the following code to index.html to create the basic HTML structure.

<!doctype html>
<html>
  <head>
    <title>HTML Sub Tag Lab</title>
  </head>
  <body></body>
</html>

Add the sub tag

Add the following code inside the <body> element to create a subscripted text.

<p>My chemical formula is H<sub>2</sub>O.</p>

This code will display the text "My chemical formula is H2O", where "2" will be displayed as a subscript.

Save the index.html file and open it in a web browser to view the output. You should see the subscripted text "H2O".

Summary

In this lab, you learned how to use the <sub> tag in HTML to display subscripted text. This is useful for displaying chemical formulas and other types of text that require a lowered baseline. By following the steps outlined in this lab, you can easily add the <sub> tag to your HTML code and create subscripted text.
