Article vs Section

These two are the most confusing semantic tags. A simple rule:

• `<article>`: could it be shared on its own and still make sense? (A blog post, a news story, a comment.) Use <article>.
• `<section>`: is it one part of a bigger whole, with its own heading? ("Features", "Pricing", "FAQ".) Use <section>.
