No, I'm pretty sure he means the readability of "absolute bottom-0 text-sm md:text-base text-white leading-relaxed tracking-tighter transition-all duration-300 ease-in-out m-3 md:m-4 px-6 md:px-8 py-4 md:py-6 opacity-0 w-full", as opposed to a single well-named class such as "image-caption".
If long class names aren't your thing, then sure, use CSS, but I'd rather save time and have understandable code than maintain those CSS classes like "image-caption".
Well, I don't appreciate the snarky comment, quite honestly. But okay, I'll assume you have had more experience than me, and you've managed things I haven't, have a good day.

Sorry, but the snarkiness was in your comment first, and when you said you didn't want to maintain those classes, that's exactly what it sounded like to me, that, well, you didn't want to maintain said code. If you had a different point I'd be happy to hear it.
