I decided to go with the bootstrap method. I’ve got the buttons and the author aligned, but things are still shifting around when you press new quote. So I could add some margin or padding to the buttons and get them in the lower left like I want, but then if the quote length changes, they’re suddenly out of the box.
EDIT: So, I played around with bootstrap a bit more and I think this is as good as it’s gonna get. The buttons and author shifting around are something that it appears I’ll have to deal with, but I at least got the buttons and author where I want them. Thanks for your help!
