I don’t like the yellow quotations behind the wording.
Buttons are a little to boring. Immediatly looks like bootstrap.
Overall: different. Not what I would do, but you used your creativity and its unique. Well done.
As a bonus, try centering the quote panel in the middle vertically. Can be challenging, see if you can do it.
Formatted nicely. I like it when people make sure it looks nice in codepen.
document.ready is well laid out. Simple and a quick helpful comment in case any confusion
good comment about p tags
not sure what the unicode things all are around line 20. Can you explain more about that?
Overall: understandable. Good job!
