The !important suggestion worked for the font size. THANK YOU!
However, for #to_top_scrollup:hover state change, I cannot achieve what I’m trying to do. When I set the #to_top_scrollup:hover state to another color!important, this CSS command changes all states of the button to that color. I’ve tried also specifying :active and :visited states at the initial color, but cannot work around this.
Any ideas other than a choice in your setup options for Hover State?
Again, happy with your plugin and am now able to use on mobile devices without the arrow being pushed way to the right (by reducing the size of the arrow on these smaller screens).
