About the CSS to Tailwind Converter

Moving a project to Tailwind means rewriting every rule as utilities, and the tedious part is not the thinking — it is remembering that 1rem is 4, that 8px is rounded-lg, and that #3b82f6 is blue-500.

Paste a stylesheet and get the classes. Spacing, sizing, colour, typography, borders, radius, shadows, flexbox, grid, position, overflow and transitions are all mapped to Tailwind’s own scale, and anything that has no place on it becomes a valid arbitrary value such as p-[13px] rather than being silently rounded. Media queries turn into responsive prefixes, :hover and ::before turn into variants, and prefers-color-scheme: dark turns into dark:. Take the result as a plain list, as ready-made HTML, or as @apply rules for a gradual migration.

Key features of the CSS to Tailwind Converter

Spacing, sizing, colour, type, borders, radius, shadow, flex and grid.

Variants from selectors

Honest about odd values

13px becomes p-[13px] rather than being rounded to something else.

Exact colour matching

Palette names only where the value matches exactly, never a near miss.

Three output shapes

A list per selector, ready-made HTML, or @apply for a staged migration.

Frequently asked questions

It keeps its exact value as text-[#123456]. Matching it to the nearest palette colour would change your design without saying so, which is worse than an arbitrary value.
