Mobile-friendly images

Please consider adding class="img-fluid"to:

• <img src="/images/repl.png" alt="repl image">
• <img src="/images/xkcd-lisp-cycles.png" alt="call-out content">

(Or on smallish screens maybe hide the bottom container wrapping the callout with the comic by adding the classes d-none d-md-block.)

Oh, nice! This is really helpful. I'm definitely not a UI person and don't know any of the CSS best practices ... good stuff.
