Create Header and Footer

[gunbux]

• Header should be absolutely positioned
• Footer always appears at the bottom of the page
• Both header and footer shall appear on EVERY page (hint:try to put the header/footer component on the app.tsx file as a component or as a wrapper to the main app component)

Tips:

• do refer/reuse to the beautifully-animated Header bar used in the rhdevs-website! (refer to navbar.tsx)
