Cómo usar: CSS to Tailwind Converter
- Paste CSS rules (with selectors) or just declarations.
- Read the class list generated for each selector.
- Copy the classes into your HTML or JSX; review arbitrary values and replace them with theme tokens where it makes sense.
How values are mapped
Tailwind’s default spacing scale uses steps of 0.25 rem (4 px), so padding: 16px becomes p-4 and margin: 0 auto becomes my-0 mx-auto. Values that are not on the scale use arbitrary-value syntax: padding: 13px → p-[13px]. Typography, radii and weights map to their named steps:
| CSS | Tailwind |
|---|---|
display: flex; flex-direction: column | flex flex-col |
gap: 16px | gap-4 |
font-size: 24px; font-weight: 700 | text-2xl font-bold |
border-radius: 12px | rounded-xl |
background-color: #7c5cff | bg-[#7c5cff] |
width: 100% | w-full |
.btn:hover { color: #fff } | hover:text-white |
Limits to know
- Colors become arbitrary values; map them to your theme palette (for example
bg-violet-500) afterwards — the CSS variables to Tailwind tool helps define a theme. - Properties without a utility are written as arbitrary properties:
[mask-image:url(...)]. - Media queries, complex selectors and animations need manual translation to
md:,group-hover:and theme config. !importantbecomes the!prefix.
For one-off values, the Tailwind arbitrary value generator builds individual classes, and the Tailwind color generator creates full palettes.
