This conference season I’ve spoken at some events for non-frontenders, suggesting that people invest time in learning the semantics of HTML. After all, there are only 120(ish) elements; the average two year old knows 100 words and by the time a child is three will have a vocabulary of over 300 words.
A few people asked me the difference between <article> and <section>. My reply: don’t worry. Simply, don’t use <section>. its only use is in the HTML Document Outline Algorithm, which isn’t implemented anywhere, and seemingly never will be. For the same reason, don’t worry about the <hgroup> element.
But do use <article>, and not just for blog posts/ news stories. It’s not just for articles in the news sense, it’s for discrete self-contained things. Think “article of clothing”, not “magazine article”. So a list of videos should have each one (and its description) wrapped in an <article>. A list of products, similarly. Consider adding microdata from schema.org, as that will give you better search engine results and look better on Apple watches.
And, of course, do use <main>, <nav>, <header> and <footer>. It’s really useful for screen reader users – see my article The practical value of semantic HTML.
Happy marking up!
