</section>Best practices
- Only use <section> when the content is thematically related and would make sense with its own heading
- If you just need a styling hook with no semantic meaning, use <div> instead
- Give each <section> a heading (<h2>-<h6>) so it makes sense in a document outline
- Do not use <section> as a wrapper purely for CSS layout purposes — that dilutes its semantic value
