So, I copied the code from the FCC exercise, added the Bootstrap CSS tag in a above it and the result is different between the two.
Notice how the buttons don’t spread the same way and the green border cat image isn’t the same size.
This is probably based on that the browser sizes are different.
I tried changing the window size of both, and I can never get them to match, plus the colors and fontawesome icons are different too.
I’m now in the jQuery exercises, and the “well” are not showing up in VS code.

Some of the thing, like the hinge, bounce animations I have tried but it doesn’t really work when I do it on codepen. The other jQuery concepts do work though(selectors, animate, DOM traversals) so it’s still relevant.
