Desktop Navbar links, logo; Mobile Navbar display

For the **desktop navbar:**
- link the logo in the top left to the path at '/' (which should lead to '/view-stock' atm)
- remove the blue link effects on :hover, :visited, :active, and any other applicable css selectors

For the **mobile navbar:**
- currently, after opening the navbar you can scroll down and see the original webpage underneath. modify this so that it covers the content below completely with a white background and cannot scroll.
- possible solution might involve creating a background div with height 100vh (or maybe less subtracting the height of the navbar itself) and setting overflow:hidden. might be other more efficient/effective solutions, this is j my instinctive first suggestion which i have not actually tried.
