• Text Formatting Tags: These tags are used to change the visual appearance of text (bold, italic, etc.) or to add semantic meaning to specific words or phrases.
• Common Formatting Tags:
  • <b> and <strong>:
    • <b>: Makes text bold for visual appeal.
    • <strong>: Makes text bold and tells screen readers that the text is important.
  • <i> and <em>:
    • <i>: Displays text in italics.
    • <em>: Displays text in italics but adds emphasis (semantic weight).
  • <u>: Used to underline text. (Note: Often avoided today to prevent confusion with hyperlinks).
  • <mark>: Used to highlight text, usually with a yellow background.
  • <small>: Renders text in a smaller font size than the surrounding text.
• Computer and Scientific Formatting:
  • <sub> (Subscript): Lowers the text below the normal line (e.g., in chemical formulas like H2O).
  • <sup> (Superscript): Raises the text above the normal line (e.g., in math like 52 or dates like 10th).
  • <del> (Deleted): Shows text with a strikethrough, indicating it has been removed.
  • <ins> (Inserted): Shows text with an underline, indicating it has been added to the document.
