scroll up button

Is your feature request related to a problem? Please describe.
instead of scrolling all the way up ,adding a button that would scroll to directly navbar when someone reaches end of page.

Describe the solution you'd like
a scroll up button

The issue names no files, tests, or entry points. Start by locating the frontend page and navbar components, then inspect how page scrolling is handled. Done means a visible control lets users at the end of the page return directly to the navbar; verify it manually at the bottom of the page.
