Button hidden behind nav menu

Correction to original Post shown below!!!
The smooth scroll up button is indeed visible ONLY after you have scrolled down! The button therefore is overlaid on top of my main navigation menu. I still need to move it’s fiscal location, so, Where and which file do I access to edit the html to allow me to raise the button up just above the navigation bar and over to the right or left a little bit? Thanks and sorry for my anxious mistaken statement.

My main navigation bar is fixed on the bottom of my pages, therefore the smooth scroll up button is behind it and not visible. Where and which file do I access to edit the html to allow me to raise the button up just above the navigation bar and over to the right or left a little bit? Thanks.

In the css folder, there are 3 files.

Depending on which type you use, you can edit the corresponding file and move the button wherever you want.

Most probably, you have to edit the bottom attribute of the #scrollUp element.

I suppose this thread is resolved.
