My portfolio project

This was great fun! Took me a while (didn’t time myself but would guess ~6 hours) because of a lot of trial and error and googling. I include links to the project on GitHub and the website on GitHub Pages.
I absolutely welcome any feedback and let me know if you find any bugs! I’ve tried to make it as responsive as possible so if it looks bad on your device then please send me a screenshot and let me know your device dimensions if you know them.
See if you can find the secret button…
