background color for the addons remains grey

Hello,

Thank you for reaching out to us. It seems the grey background is part of your image, while the card background you’ve applied is set to white. If you’d like the image background to be white, you’ll need to edit the photo itself.

Thanks!

Hello,

Could you please provide us with your admin access in the hidden content section? This will allow me to assist you more effectively. Before this, I will recommend you to keep your full site backup.

Edit:

Or you can do it by this way:

use this css in your custom css in style, Please do it for each feature box addon.

#addonId{
    background-color: white !important;
}

Thanks!
