The black border around the collapsible content extended edge-to-edge on the user’s site
In the official Taste demo, the same section had a maximum width that aligned with product images

Solution Provided:
A CSS fix was shared to add to the base.css file:
Resolution:
The user confirmed the CSS solution successfully resolved the width issue. An alternative suggestion to adjust the section’s Layout settings in Theme Customization was also mentioned but not ultimately needed.

In the Taste theme, when I create collapsable content (titled “frequently asked questions” in the image below), it always defaults to full screen width (see image below).
No. When I full screen, the box for the black border around frequently asked questions on my site extends the full with of the page. However, in the taste demo, it appears to have a fixed maximum width (i.e., when you full screen, the black border does not extend the full width of the page - and is not edge to edge).
Also, if you want to have border same as demo site then you can change setting in your Online store > Themes > Customize > Theme settings > Content containers
