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.
