What is the "aside" element that is an example?

The <aside> element in HTML is used to represent content that is tangentially related to the content around it. It's often used for sidebars, pull quotes, advertisements, or other content that is separate from the main content flow but still relevant to it.

For example, consider a blog post about the history of coffee. The main content might discuss the origins of coffee, how it's cultivated, and its journey to becoming a popular beverage. An <aside> element could contain information about the health benefits of coffee or a brief history of a famous coffee brand. This information isn't essential to understanding the core history, but it does provide related and contextual information.

Here’s an example of how the <aside> element might be used within a website:

<article>
  <h2>The History of Coffee</h2>
  <p>...Main content about coffee history here...</p>

  <aside>
    <h3>Health Benefits of Coffee</h3>
    <p>Studies have shown that coffee can...</p>
  </aside>
</article>
                            

In this case, the <aside> contains additional, though secondary, information about coffee. The content within an <aside> should always be related in some way to the content around it but should be able to stand on its own as supplemental information.
