In HTML, text formatting tags are used to enhance the appearance and meaning of text content on a web page. These tags allow developers to emphasize certain parts of the text, structure content, and improve readability. Most of these tags are semantic, meaning they not only change the visual style but also convey the significance of the text to browsers and assistive technologies like screen readers.

The <b> tag is used to make text bold without implying any extra importance, while the <strong> tag also displays text in bold but indicates that the content has strong importance or urgency. Similarly, the <i> tag renders text in italic for stylistic purposes, such as foreign words or thoughts, whereas the <em> tag is used for emphasized text and conveys stress emphasis, making it more meaningful for accessibility.

The <u> tag underlines text, often used to indicate misspelled words or special annotations, while the <mark> tag highlights text with a background color, useful for drawing attention to key information. The <small> tag is used to display side comments or fine print in a smaller font size, typically for disclaimers or copyright notices. The <sub> and <sup> tags are used for subscript and superscript text, respectively, which are essential for mathematical formulas, chemical equations, or footnote references.

Additionally, the <del> tag represents deleted text by showing a strikethrough, often used in documents to indicate removed content, while the <ins> tag indicates inserted text, usually displayed with an underline. These tags help in tracking changes in a document. HTML also supports semantic tags like <code> for inline code snippets, <pre> for preformatted text, and <q> or <blockquote> for quotations, which maintain formatting and provide context.
