Any comments on my Quote Machine

This task wasn’t really as hard as I originally thought but still I want feedback to make sure everything was done correctly. If there are any ways I could make my code more efficient that would be very helpful.

Here is my project:

I like the layout! My feedback would to use a different font and maybe a background picture that is a little bit more clear. If you look through the Google fonts there are some really nice ones!
