What is the HTML SubScript tag
✷ The HTML <sub> tag is used to display text slightly below the normal line. This type of text is called subscript text and is commonly used in chemical formulas, mathematical expressions, and scientific writing.
✷ The syntax of the <sub> tag is very simple:
<sub>text</sub>
✷ When you place text inside the <sub> tag, the browser automatically shows it in a smaller size and lowers it below the baseline. This makes it perfect for writing formulas like water:
✷ H<sub>2</sub>O
✷ This will display as H₂O, which is the correct scientific format.
✷ The <sub> tag is also useful in mathematics, for example:
x₁, x₂, x₃
✷ It is an inline element, meaning it does not start on a new line and can be used inside paragraphs, headings, or other text content without breaking the layout.
✷ There is also a related tag called <sup>, which is used to display text above the line (superscript).
