Let me organize these questions to make it easier for you.

1. How do I remove the grey colored bar at the bottom of the page? I believe this is the background as I know how to change the color although I want to complete remove the grey bar entirely. It looks strange.
2. I would like to remove the navigation bar entirely? I don’t think it serves my purposes.
3. Is there a way to set up mailchimp to collect the email addresses instead of it going to an inbox I manage? I would like to keep the same look within the template on the contact form but use mail chip if that makes sense?
4. I notice the website doesn’t display nicely on desktops? I would like the website to show up correctly on any device.

Thank you in advance for your support!
