Responsive design accordion

What are you most proud of, and what would you do differently next time?

Happy to have figured out most of the JavaScript on my own with just a little help from the internet.

What challenges did you encounter, and how did you overcome them?

It took me a little bit to figure out how to order the code so that the plus and minus signs would switch appropriately and would line up with when the answers were shown.

What specific areas of your project would you like help with?

Couldn't figure out the best way to set media queries for this one for a good user experience. I felt like I just ended up selecting something I thought looks nice. What are the methods to finding "break points?"

My particular issue was figuring out when to switch the background images from the mobile version to the desktop version in a way that wouldn't be too jarring for a user.
