To create a collapsible section in your webpage, you can use the HTML

and

elements. This provides a simple way to hide and reveal content without needing JavaScript.

<!-- BEGIN COPY / PASTE -->
    <details>
      <summary>Click to expand</summary>
      <p>This is the content that can be collapsed or expanded.</p>
    </details>
    <!-- END COPY / PASTE -->

Additional Comment:

The <details> element creates a widget that users can open and close.
The <summary> element acts as a label for the <details> element and is always visible.
Content inside the <details> element is hidden by default and shown when the user clicks the <summary>.
