Someone can fact check me, I'm going off memory: I believe in v1 Tailwind (before they added the "JIT" compilation) when you were in dev mode it just had all the classes available at all times, and then added a step to the prod build where it would purge unused classes from the CSS. Now Tailwind scans for which classes are used as you add them and builds an output from that. So if you only used `m-auto` the only CSS it would output in the final build is .m-auto { margin: auto; }
