Hello,
1. I’ve created “Footer makeup test” as on our demo. Please check it http://prntscr.com/h7du5b.
2. This content is our default but isn’t visible in widger areas. You may simply replace it (add a Text widget with your text).
3. Edit this element of Home page http://prntscr.com/h7dvub
Seems you changed theme on your site. So I can’t provide an example of code, but likely this problem can be solved via adding Custom css code.
Regards
