How CSS properties map to Tailwind utility classes
What is CSS to Tailwind Conversion?
CSS to Tailwind conversion is the process of replacing plain CSS property/value declarations with equivalent Tailwind CSS utility classes. For example, display: flex becomes flex, padding: 1rem becomes p-4, and font-weight: 700 becomes font-bold. Our css to tailwind converter analyzes each CSS declaration and looks up the closest Tailwind utility class from a comprehensive mapping of 200+ CSS properties. Declarations without direct Tailwind equivalents are flagged separately so you can handle them with arbitrary values or custom CSS.
How Our CSS to Tailwind Converter Works
- 1. Paste Your CSS: Enter CSS declarations with or without a selector. The converter accepts bare declarations (
display: flex; padding: 1rem;) or full CSS rules with selectors. All processing happens locally in your browser — your CSS never leaves your device. - 2. Instant Mapping: Click Convert to Tailwind. The converter parses each declaration, normalizes the property and value, and looks up the matching Tailwind class. Choose space-separated, JSX className, or HTML class output format.
- 3. Review and Copy: View the matched Tailwind classes and the list of unmatched declarations. Copy the output with one click for use in your JSX or HTML.
CSS to Tailwind Mapping Examples
- display: flex → flex
- flex-direction: column → flex-col
- align-items: center → items-center
- justify-content: space-between → justify-between
- padding: 1rem → p-4
- margin-top: 0.5rem → mt-2
- font-size: 0.875rem → text-sm
- font-weight: 700 → font-bold
- border-radius: 0.5rem → rounded-lg
- cursor: pointer → cursor-pointer
Limitations and Arbitrary Values
Not every CSS value has a direct Tailwind equivalent. Custom values, non-standard sizes, and complex CSS properties may not match any Tailwind class. For these cases, Tailwind supports arbitrary values — for example, w-[200px], text-[#ff0000], or mt-[13px]. Our css to tailwind converter flags unmatched declarations so you can decide whether to use arbitrary values, keep the CSS, or refactor the design to use standard Tailwind spacing and color scales.
