Mixed Messages Project: Random Quirky Messages

Hey guys, just completed my first portfolio project.

I found it pretty challenging to put the program together, since I have not yet learnt how to add Javascript to an existing HTML document. However after a lot of research, trial and error, I made way through! It took me about a week to complete. Please see below a link to my live website and repo:

Repo: GitHub - Aimes13/Mixed-Messages-Portfolio-Project: Codecademy portfolio project on JavaScript II, Git & GitHub

Any feedback or constructive criticism on how to improve the code quality is welcome.
