Hello,

I have seen your screenshot. If you want to adjust the margin of green boxes. You have to define your custom CSS class in that specific row which contains those “Promo Banners”.
I have defined the “promoBan” custom Class you can check in the below screenshot: https://jmp.sh/AScTYPB

After defining class you have to use the below CSS code in the page CSS area:

.promoBan .wrapper-content-banner{
    margin-left:50px;
}

Screenshot for clarification: https://jmp.sh/a7S3KBX

Result: https://jmp.sh/VDgRVui

To remove the box you can edit the banner and remove the title and subtitle and save the changes

Best Regards.
