Banner Ads in Header

Plug-ins for ads are extremely bloated and I didn’t want to use any of the ones I tried. So, for now, I just put the code into the theme files. That will need to be replaced each time we update the theme until we can make a child theme or find another way. Go to Appearance > Editor and then select header.php (make a copy of it first in cPanel file manager and delete the old copy so we have a copy from the updated theme).

(use Code Snippets plug-in instead of re-doing after each update)
