Superscript is used to display text above the baseline, while subscript is used to display text below the baseline. In HTML, these effects can be achieved using the <sup>
and <sub>
elements, respectively.
Superscript: <sup>
Example:
HTML
<p>H<sub>2</sub>O is the chemical formula for water.</p>
<p>2<sup>3</sup> equals 8.</p>
Subscript: <sub>
Example:
HTML
<p>H<sub>2</sub>O is the chemical formula for water.</p>
<p>2<sub>3</sub> is not a common mathematical notation.</p>
Note:
- Both
<sup>
and<sub>
are primarily used for presentation purposes and don't convey any specific semantic meaning. - They are often used for mathematical formulas, chemical notation, and other specialized content.
Additional Considerations:
- You can combine superscript and subscript within the same element.
- For more complex mathematical expressions, consider using LaTeX or specialized mathematical notation tools.
By using <sup>
and <sub>
, you can effectively display superscript and subscript text in your HTML documents, enhancing the readability and accuracy of content that requires these formatting elements.
