HTML5 Semantic Elements — AnchorFact

## TL;DR

HTML5 (2014) introduced semantic elements that describe their meaning to both browser and developer: `

`, `

`, `

`, `

`, `

`, `

`, `

`, `

`, ``. They improve accessibility (screen readers), SEO, and code readability.

## Core Explanation

`

` should be used once per page (dominant content). `

` for self-contained, independently distributable content. `

` for thematic grouping with a heading. `

` for tangentially related content. Semantic HTML provides implicit ARIA roles — `

` = role='navigation', `

` = role='main'. Always prefer semantic elements over `

`.
