TaskBuild a blog page: <main> contains an <article> with <h1>My post</h1> and <p>First paragraph</p>. After that article, add a second <article> with <h2>Comment</h2><p>Great post.</p>.
<article> vs <section>: when each is right

Theory
The single test that resolves the article-vs-section debate
Ask: "Could this content stand alone on its own page (RSS, syndication, separate URL) and still make sense?"
- Yes →
<article>. Blog posts, product cards, tweets, comments, news items. - No →
<section>(when you also need a heading). It's a thematic group within a bigger thing.
<main>
<article>
<h1>Why I left Vim for VS Code</h1>
<p>Date: 2026-05-20…</p>
<p>For 15 years I used Vim…</p>
</article>
</main>That <article> could be syndicated to RSS, copied to a planet aggregator, or rendered standalone. It's self-contained.
<article>
<h1>Annual Report 2025</h1>
<section>
<h2>Financial highlights</h2>
<p>…</p>
</section>
<section>
<h2>Team growth</h2>
<p>…</p>
</section>
</article>The <section>s only make sense inside the report. Each has its own <h2> (every <section> SHOULD have a heading — that's the rule).
When NOT to use <section>
If you just need a styling wrapper and there's no heading → use <div>. <section> without a heading is technically a misuse (axe will warn). <div> is fine for layout-only grouping.
