The <section> tag is used to group related content that shares a common topic or theme — like a chapter in a book or a section of a page.
The <article> tag is for content that can stand on its own, such as a blog post, news article, or forum post. Even if it’s taken out of the page, it still makes sense by itself.
The <aside> tag is used for extra or related content that supports the main content, like a sidebar, ads, or related links.
Here’s a simple example 👇
<section>
<h2>Technology News</h2>
<article>
<h3>New Smartphone Launch</h3>
<p>Today a new smartphone was launched with exciting features.</p>
</article>
<article>
<h3>AI Advancements</h3>
<p>AI is transforming industries worldwide.</p>
</article>
</section>
<aside>
<h3>Related Links</h3>
<ul>
<li><a href="#">Top Gadgets 2025</a></li>
<li><a href="#">AI in Healthcare</a></li>
</ul>
</aside>
✅ In short:
<section>= a group of related content<article>= a self-contained piece of content<aside>= extra or related information on the side
