Changes made in "Costumize", not present when choose "view site"

I feel like I must be doing something very basic incorrectly.

When working in Appearance>Customize. I make changes to the theme and they look/work fine.

However, when I switch to “View Site” none of those changes appear. When I switch back into “Customize” all the changes are present.

What am I missing? I don’t want to take the site live if the changes don’t stick…

Thanks so much!
