Pulled and ran tests. No issues found with the refactor from scss styling to tailwind.

Also, from my understanding memory router was added to the test scripts because the landing page was utilizing link components. Should that mean we also add memory router at the top level of all our routes? Additionally, should we also refactor all anchor tags pointing to a different browser URL to utilize link components instead?

Thanks for reviewing my PR, @bennyv8 !

I added so Jest can test the page that now uses instead of . I suppose we need to do this when testing any page that uses routing context. Maybe there is an easier way.

I prefer to anchor tags for UX and preserving state, but maybe instead of refactoring all anchor tags at once, we can replace them with as we encounter them?
