Chapter 2 — Text formatting, Links & Images

• Text formatting tags:
  • <strong> (important/bold), <em> (emphasis/italic)
  • <mark> (highlight), <small>, <del> (deleted), <ins> (inserted)
• Hyperlinks (links):<a href="https://example.com">Visit site</a> <a href="#section1">Jump to section</a> <!-- internal link --> <a href="mailto:me@example.com">Email me</a>
  • target="_blank" opens in new tab; rel="noopener" recommended for safety.
• Images:<img src="image.jpg" alt="description" width="300">
  • alt text is essential for accessibility and SEO.
  • Use proper formats (JPEG for photos, PNG for transparency, SVG for scalable icons).
• Inline vs block elements:
  • Inline (e.g., <a>, <img>) do not start on a new line.
  • Block (e.g., <p>, <div>, headings) start on a new line and can contain other elements.
• File paths: relative vs absolute (use relative for local site links).
