More CSS Changes

Also, there is a new banner for the garden tour and gala so take a look
and let me know what you think! In addition, I have commented out the
fading in and out of the back to top for better functionality between
desktop and mobile (least for now).
Also, the donate button and escape button are now also on the mobile
site but their location is completely up in the air so let me know your
thoughts on that as well!
Hope you like the changes, and feel free to bring up anything you
dislike
