PurgeCSS configuration gotchas and dynamic class generation failures

6/10 Medium

Incorrect PurgeCSS setup causes unused class removal to break dynamically generated classes at runtime. Classes constructed via string interpolation (e.g., `object-position-[x y]`) fail to parse correctly, negating Tailwind's performance benefits.

Query: “What are the most common pain points with Tailwind CSS for developers in 2025?”4/5/2026

`object-position-[x y]` wouldn't even work because there's a space between x and y when there should be an underscore. Also, calc doesn't work on those as well.
