πŸ™‹ Introduction

In the HTML markup language, the <sub> tag plays a crucial role in defining subscript text. This guide aims to provide a comprehensive understanding of the <sub> tag and how to effectively implement it in your web development projects.

πŸ€” What is <sub> Tag?

The <sub> tag is an essential HTML element used to render text or characters in a subscript style. Subscripted text appears slightly below the baseline, often employed for mathematical notations, chemical formulas, and footnotes.

πŸ’‘ Syntax

To utilize the <sub> tag, enclose the text or content you want to appear in subscript within the opening <sub> and closing </sub> tags.

🧰 Attributes

The <sub> tag typically does not require additional attributes. However, you can combine it with other tags or attributes to achieve specific styling effects if needed.

<p>This is a chemical formula: H<sub>2</sub>O</p>

πŸ“š Common Use Cases

  1. Mathematical Notations:

    The <sub> tag is commonly used in mathematical expressions to represent indices or subscripts.

    <p>The area (A<sub>1</sub>) of the first circle is smaller than the area (A<sub>2</sub>) of the second circle.</p>
  2. Footnotes:

    In academic or content-rich websites, the <sub> tag can be employed to display footnotes in a visually distinct manner.
