Todo app main using Bootstrap 5 and vanilla JS

Hi Clifford, awesome job on the app! I especially loved that you disabled the navigation button when no items are in that state (for example, Completed nav is disabled if none of the items are completed yet).

You would want to check on your light theme because when I added an item while I'm in light mode, it switched back to dark mode. Adding top and bottom padding on the create a new to-do div can give a more consistent style with the bottom portion of the to-do lists.

All in all, great job!
