Use Case

Migrate Chakra UI to Tailwind CSS

Chakra's style props and theme tokens live in JSX, not in CSS files. ExtractCSS reads the final computed styles from the browser and converts them directly to Tailwind utility classes.

{THE PROBLEM}

Chakra's style props are powerful to write and painful to migrate away from.

Chakra UI lets you write styles as React props: <Box p={4} bg="blue.500" borderRadius="lg">. Responsive values use array syntax: px={[2, 4, 8]}. Theme tokens like blue.500, sm, and lg resolve through Chakra's theme at runtime.

None of this exists in a CSS file. Styles are scattered across JSX props, spread through component abstractions, and resolved by Chakra's runtime. A static converter cannot follow the chain from p={4} to the actual padding: 1rem without reimplementing the theme resolution logic.

Teams moving from Chakra to Tailwind typically face three challenges: mapping Chakra's token names to Tailwind equivalents, translating responsive array props to media-query prefixes, and handling the custom theme extensions that override default spacing, colors, and border radius values. Doing this manually across a full application takes days.

{THE SOLUTION}

Read the rendered output, not the style props.

ExtractCSS does not parse your Chakra style props or theme config. It reads the computed styles the browser applied after Chakra's runtime resolved every token, responsive array, and theme extension. By the time ExtractCSS sees a component, the browser has already turned bg="blue.500" into a concrete background-color value.

A Chakra <Button colorScheme="teal" size="lg"> becomes something like bg-teal-500 text-white px-6 py-3 rounded-md font-semibold text-lg. Not because ExtractCSS has a Chakra-to-Tailwind lookup table, but because those are the actual values the browser rendered.

It works with Chakra v1 and v2. It works with custom theme extensions, component variants, and multi-part component styles. If the browser can render it, ExtractCSS can read it.

How it works

  1. 1

    Open your Chakra app in Chrome

    Navigate to the page you want to migrate. Localhost, staging, or production all work. Chakra's runtime and your ChakraProvider are already loaded in the browser.

  2. 2

    Select the component to convert

    Activate ExtractCSS and hover over any element. Click to capture the component and all its children. Chakra's internal markup is captured along with it.

  3. 3

    Adjust the tolerance

    Chakra's default spacing scale (multiples of 4px) aligns well with Tailwind's. The "Balanced" tolerance setting handles most Chakra components cleanly. Tighten it if you need exact fidelity on colors or shadows.

  4. 4

    Copy the Tailwind HTML

    The output panel shows clean HTML with Tailwind utility classes. Use the live preview to compare the result against your original Chakra component before pasting.

Common Chakra patterns and how they convert

Chakra's style props, responsive arrays, and theme tokens all resolve to standard CSS before ExtractCSS reads them. Here is how common patterns translate.

Style props and shorthand

Chakra's <Box p={4} mt={2} bg="gray.100"> compiles to inline Emotion styles at runtime. The browser applies padding: 1rem, margin-top: 0.5rem, and a background color. ExtractCSS reads those values and maps them to p-4 mt-2 bg-gray-100. The names look similar because both frameworks use similar spacing scales, but the mapping happens through computed values, not name matching.

Responsive array syntax

Chakra's fontSize={['sm', 'md', 'lg']} generates media-query-scoped CSS rules for each breakpoint. ExtractCSS captures these as responsive Tailwind prefixes: text-sm md:text-base lg:text-lg. The breakpoint values come from your Chakra theme, not from a static lookup.

Theme tokens and custom colors

Custom theme extensions that add colors like brand.500 or override spacing tokens resolve to concrete CSS values before ExtractCSS reads them. A custom brand.500: "#6d28d9" becomes bg-violet-700 because that is the nearest Tailwind design token. Use the color panel to swap it if you prefer a different shade.

Multi-part components and variants

Chakra's multi-part components like Tabs, Menu, and Accordion apply styles to multiple internal elements through the component style config. ExtractCSS captures every element in the tree, so each part gets its own Tailwind classes. A <Tabs variant="enclosed"> produces separate Tailwind classes for the tab list, individual tabs, and the tab panel.

Why computed styles beat prop-by-prop translation

A source-level converter would need to parse every Chakra style prop, resolve theme tokens, evaluate responsive arrays against breakpoints, and handle pseudo-prop shorthands like _hover and _focus. It would also need to trace theme extensions, component variants, and style config overrides. That is effectively rebuilding Chakra's styling engine.

ExtractCSS skips all of that. Chakra's Emotion runtime has already done the work: injected the style tags, resolved the tokens, applied the cascade. ExtractCSS reads the final answer from the DOM. There is no ambiguity about which theme token was used or how a responsive array evaluated at the current viewport.

This approach also handles hybrid projects that mix Chakra style props with plain CSS, CSS modules, or @emotion/styled. ExtractCSS does not care where the styles originated. It reads what the browser rendered.

Tips for a smooth migration

  • 1.Migrate one page or feature at a time. Chakra and Tailwind can coexist in the same project. Convert a settings page, a dashboard card, or a form, and verify it before moving on.
  • 2.Use the token panels to align color palettes. Chakra's default palette diverges from Tailwind's at several shades. The color panel shows every value in the extracted component. Swap Chakra's teal.500 for your Tailwind theme color before copying.
  • 3.Check responsive behavior at each breakpoint. Chakra and Tailwind use different default breakpoint values. After extraction, resize your browser and compare the Tailwind output against the original to catch any breakpoint mismatches.
  • 4.Simplify the HTML after extraction. Chakra's Box, Flex, and Stack components render as plain divs. Once you have the Tailwind classes, you can often flatten or remove wrapper elements that Chakra needed but Tailwind does not.
