How to read this

  • Most tags come in pairs, opening and closing. Only tags with no content — img, br — are left unclosed.
  • Writing </br> for a void element does nothing useful; the browser ignores it or adds an empty line.
  • Appearance is CSS’s job. A tag says what something is; bold or italic is only the consequence.
  • Choosing the tag that matches the meaning helps search engines and screen readers alike. Wrapping everything in div throws that information away.
