When should I convert Tailwind classes to plain CSS?
Convert when migrating away from Tailwind, exporting a component for a project that doesn't use Tailwind, building email templates that need inline styles, or extracting styles into a design system's base layer. Plain CSS gives you portability and removes the Tailwind build dependency. Keep Tailwind classes in normal projects where the utility-first workflow is part of your team's conventions.
Why convert plain CSS to Tailwind?
Useful when adopting Tailwind in an existing project, replacing one-off custom CSS with reusable utilities, or learning Tailwind by translating familiar styles. The converter maps properties to their nearest Tailwind utility and flags values that don't fit Tailwind's default scale, helping you decide whether to extend the config or accept arbitrary values like `w-[123px]`. Always review the output before committing.
How does the converter handle responsive prefixes?
Tailwind's `md:`, `lg:`, etc. prefixes correspond to media queries with min-width breakpoints. The converter wraps the converted CSS in matching `@media` blocks. Going the other way, it groups same-breakpoint properties under a single prefix where possible. Custom breakpoints from your `tailwind.config.js` aren't automatically detected, so verify mapped breakpoints match your project's configuration.
Does the converter support arbitrary values like `w-[27px]`?
Yes. Arbitrary values translate directly to plain CSS (`width: 27px`), and unusual plain CSS values that don't match Tailwind's scale are converted to bracketed arbitrary utilities. Be aware that arbitrary values increase Tailwind's build output, so prefer extending your theme for repeated values and reserving arbitrary syntax for one-off cases.
Can I convert Tailwind's `space-x` and `divide` utilities?
These compile to `> * + *` selectors in plain CSS, which the converter outputs as-is. The reverse direction (plain CSS to Tailwind) recognizes the pattern and suggests `space-x-*` or `divide-*` utilities. If your CSS uses gap (preferred in modern flex/grid layouts), the converter maps it to `gap-*` utilities, which behave differently and don't require the adjacent-sibling selector trick.
What about Tailwind's state variants like `hover:` and `focus:`?
These translate to corresponding pseudo-class selectors: `hover:bg-blue-500` becomes `&:hover { background-color: #3b82f6; }`. Group hover (`group-hover:`) and peer (`peer-hover:`) translate to selectors using the parent's `.group` class or sibling `.peer`. The converter preserves the relationship structure but you may need to manually add the `.group` or `.peer` classes to the parent/sibling element in your HTML.
