Changed the fonts and size of text

[Uttkarsh09]

Added basic font formatting and CSS to make it look a bit better along with some minute changes in HTML.

Fixes #3 & #17.

I tried changing the background mentioned in #16 in this as well, but it didn't look nice. (I know that looks aren't the main goal of this repo but yeah 😅)
