Questions about the Semantic HTML poster

What’s on the Semantic HTML poster?

A 8-row table: Element · For. Each of these tells a browser, a screen reader and a search engine what the content is. <header> / <footer> — Top and bottom of a page or section; <nav> — A block of navigation links; <main> — The primary content — one per page; <article> — Self-contained, redistributable content; <section> — A thematic group, usually with a heading; <aside> — Tangential content; <button> — Anything that performs an action; <a> — Anything that goes somewhere. A div with a click handler is not a button: no keyboard focus, no Enter or Space, no announcement. Use the element.

Who is the Semantic HTML poster for?

Semantic HTML belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning the web can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Semantic HTML poster?

Reach for a semantic element first. A div is what you use when nothing else fits. A wall chart earns its place by being glanceable from where the work is happening, so Semantic HTML belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.

What other posters go with Semantic HTML?
