Does this handle all CSS properties?

It handles the most commonly used properties including layout (flex, grid), spacing (margin, padding), typography, colors, borders, shadows, and more. Some complex or shorthand properties may not convert and are flagged for manual review.

Can I paste a full CSS file?

Yes. The converter strips selectors and braces, extracting only property-value pairs. You can paste entire rule blocks or individual declarations.

Does it support Tailwind v4?

The converter outputs standard Tailwind utility classes compatible with both Tailwind v3 and v4. Arbitrary value syntax [value] can be used for properties that do not have a direct mapping.

About CSS to Tailwind Converter

Converts CSS property declarations to their equivalent Tailwind CSS utility classes. Paste raw CSS — individual declarations or full rule blocks — and get the Tailwind output ready to drop into your JSX. The converter handles layout (display, flexbox, grid), spacing (margin, padding), sizing (width, height), typography (font-size, font-weight, line-height, letter-spacing), colors, borders, border-radius, shadows, opacity, positioning, and overflow. Tailwind uses a design token system where values like 16px map to named scales (p-4, m-4) rather than arbitrary pixel values. The converter maps standard sizes to Tailwind scale values where an exact match exists. When no direct class exists — for example, a non-standard font-size or a custom box-shadow — it outputs the Tailwind arbitrary value syntax (text-[13px], shadow-[0_4px_12px_rgba(0,0,0,0.15)]) so the output is always valid and functional. This is particularly useful when migrating a legacy CSS codebase to Tailwind incrementally, converting HTML email templates to Tailwind components, or when you have a designer who writes raw CSS and you need to translate their specs into Tailwind as you implement.
