HTML <sup> and <sub> Examples

The <sup> and <sub> tags in HTML are used to display superscript (raised text) and subscript (lowered text). Superscript is commonly used in math formulas (like x²) or footnotes (like 1^st), while subscript is used in chemical formulas (like H₂O). These tags help format text in scientific, academic, or technical content for better readability and structure.
