Theme Button Positioning

[alextsagkas]

In small screens (e.g. mobile screens) the right-20 style pushes the button near the center of the screen and it looks odd. I would recommend to change that to something like right-5 which seems nicer.

Personal Touch: I incorporated some minor opacity so as the content to be more readable on a small screen. You could try that and decide if this makes the content more readable in smaller screens.
