Hi,
The Container element from the Elementor plugin has a default content width of 100%, which prevents it from being narrowed using the margin property. These container styles, like the element itself, are part of Elementor, and our theme does not affect their behavior.
If you want to reduce the content width of the container, you should use the padding property (https://monosnap.com/file/J1F2j0CtBiGMdqU2JU7LM3OJO5ry2d) or adjust the content width option (https://monosnap.com/file/c5rlaOZdxsGQEicEkogXlZ0sGgwz5P).
If none of these options work for you and you still want to use margin, you must first disable the default 100% width set in the container by:
1. Setting Content Width to Full Width.
2. Switching Width value to Custom.
3. Entering “unset” in the width field as shown on screenshot https://monosnap.com/file/QFdIEUkjMpvgJK4p2f6ZkIPXjQP3kZ
Kind Regards
