Hi, Jonah.
Thanks for your comment regarding the Resolve Inspiration you are using. I just installed this Inspiration on my own website to review the appearance. It looks like the rectangular box is part of the design.
BoldGrid allows you to manipulate the CSS to provide more in-depth customization. Using Google Chrome’s Developer Console, I was able to edit the CSS live and provide the following code as a solution to changing this aspect of your site:
.palette-primary .background-accent {
background: transparent;
!important;
}
Simply add that code to the CSS Editor in BoldGrid’s Customizer and then you will see the rectangular “accent” is now transparent/invisible. I hope this helps!
Sincerely,
Carlos E
