I'm working on a new website. How can I make the Frontend look better? (Homepages & Subpages))

Hey All!

I’m working on a site that lets you view footage from cities around the world… utilizing the YouTube Embedded Player. It’s just a little side project cause I’m bored while stuck at home, I don’t expect it to be much…

However, I really want it to be looking top notch cause I plan to show it to some of my friends and family.

How could I modify the HTML, CSS & JS code to make the site look better? (Especially the page that hosts the embedded player)
