Make frontend site more responsive

[hdavidethan]

Requirements:

• Familiarity with HTML/CSS
• Some React experience (can be learned)

Ideally, we want the frontend site to be viewable on most devices (responsive to screen size). If possible, adjust the UI elements to display information more efficiently.

Since we currently use Sematic UI React as our frontend UI framework, please review the docs (especially Grid, Container, and Layout): https://react.semantic-ui.com/
