Hello,
The space on the left and right side of your banner is usually caused by the layout settings of the page or the section containing the banner. To make the banner full width, please follow these steps:
1. Edit the page (Homepage)
Go to your page editor (Elementor).
2. Set the section to Full Width:
Edit the banner section.
Set Content Width to Full Width.
Enable Stretch Section (if available).
Make sure there is no padding or margin on the left and right (set both to 0).
If the issue still persist, please share your site WP Admin URL and Credentials under the private content area of this topic, so that I can have a look into it for you on your site and help you out.
Best Regards,
