In this section, we will explore various HTML tags used to format text. These tags help you emphasize, highlight, and structure text content on your web pages. Understanding these tags is crucial for creating well-structured and visually appealing web content.

Key Concepts

  1. Bold Text (<b> and <strong>):

    • <b>: Makes text bold without implying any extra importance.
    • <strong>: Makes text bold and indicates that the text is of strong importance.
  2. Italic Text (<i> and <em>):

    • <i>: Italicizes text without implying any extra emphasis.
    • <em>: Italicizes text and indicates that the text should be emphasized.
  3. Underlined Text (<u>):

    • <u>: Underlines text, often used for stylistic purposes.
  4. Strikethrough Text (<s> and <del>):

    • <s>: Strikes through text, indicating that it is no longer accurate or relevant.
    • <del>: Strikes through text, indicating that it has been deleted.
  5. Subscript and Superscript (<sub> and <sup>):

    • <sub>: Displays text as subscript, typically used for chemical formulas or mathematical expressions.
    • <sup>: Displays text as superscript, often used for exponents or footnotes.
  6. Small Text (<small>):

    • <small>: Reduces the font size of the text, often used for fine print or disclaimers.
  7. Inserted Text (<ins>):

    • <ins>: Underlines text to indicate that it has been inserted.
  8. Marked Text (<mark>):

    • <mark>: Highlights text, indicating that it is important or relevant.

Exercise: Create an HTML page that uses each of the text formatting tags discussed above.

Solution:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Text Formatting Tags</title>

    <p>This is a <del>deleted</del> text.</p>
    <p>H<sub>2</sub>O is the chemical formula for water.</p>
    <p>E = mc<sup>2</sup> is Einstein's mass-energy equivalence formula.</p>
    <p>This is a <small>small</small> text.</p>
    <p>This is an <ins>inserted</ins> text.</p>
    <p>This is a <mark>highlighted</mark> text.</p>

Common Mistakes and Tips

  • Misusing <b> and <strong>: Use <strong> when the text is of strong importance, not just for styling.
  • Confusing <i> and <em>: Use <em> to emphasize text, not just for styling.
  • Overusing <u>: Underlining is often reserved for links, so use it sparingly to avoid confusion.
  • Forgetting to close tags: Always ensure that you close your tags properly to avoid rendering issues.
