My apologize for the delay and for the inconvenience.
I’ve checked your site again but still didn’t see the blue section.
"The blue section is above the footer, where the introduction text is. I would like the Home page to just be a giant picture with a header and footer, if possible."
Yes, firstly you have to:
- set the home page template as “Front page” (Edit the home page, you’ll see the template option on the right side)
- set your home page as a static page from customize > static front page
- set the header image from customize > header area
Here is the steps to create service page:
- Set your service page template as widgetized
- go to customize > widget (make sure you open the service page http://prntscr.com/dgbl0q)
- Add "Astrid FP: Service widget"
for the service icon, make sure you upload a featured image to your service items.
