The magic of Tailwind with the flexibility of css-in-js.

---

Style jsx elements using Tailwind classes:

1import 'twin.macro'
2
3const Input = () => <input tw="border hover:border-black" />

Nest Twin’s tw import within a css prop to add conditional styles:

1import tw from 'twin.macro'
2
3const Input = ({ hasHover }) => (
4  <input css={[tw`border`, hasHover && tw`hover:border-black`]} />
5)

Or mix sass styles with the css import:

1import tw, { css } from 'twin.macro'
2
3const hoverStyles = css`
4  &:hover {
5    border-color: black;
6    ${tw`text-black`}
7  }
8`
9const Input = ({ hasHover }) => (
10  <input css={[tw`border`, hasHover && hoverStyles]} />
11)

Styled Components

You can also use the tw import to create and style new components:

1import tw from 'twin.macro'
2
3const Input = tw.input`border hover:border-black`

And clone and style existing components:

1const PurpleInput = tw(Input)`border-purple-500`

Switch to the styled import to add conditional styling:

1import tw, { styled } from 'twin.macro'
2
3const StyledInput = styled.input(({ hasBorder }) => [
4  `color: black;`,
5  hasBorder && tw`border-purple-500`,
6])
7const Input = () => <StyledInput hasBorder />

Or use backticks to mix with sass styles:

1import tw, { styled } from 'twin.macro'
2
3const StyledInput = styled.input`
4  color: black;
5  ${({ hasBorder }) => hasBorder && tw`border-purple-500`}
6`
7const Input = () => <StyledInput hasBorder />

How it works

When babel runs over your javascript or typescript files at compile time, twin grabs your classes and converts them into css objects. These css objects are then passed into your chosen css-in-js library without the need for an extra client-side bundle:

1import tw from 'twin.macro'
2
3tw`text-sm md:text-lg`
4
5// ↓ ↓ ↓ ↓ ↓ ↓
6
7{
8  fontSize: '0.875rem',
9  '@media (min-width: 768px)': {
10    fontSize: '1.125rem',
11  },
12}

Features

👌 Simple imports - Twin collapses imports from common styling libraries into a single import:

1- import styled from '@emotion/styled'
2- import css from '@emotion/react'
3+ import { styled, css } from 'twin.macro'

🐹 Adds no size to your build - Twin converts the classes you’ve used into css objects using Babel and then compiles away, leaving no runtime code

🍱 Apply variants to multiple classes at once with variant groups

1import 'twin.macro'
2
3const interactionStyles = () => (
4  <div tw="hover:(text-black underline) focus:(text-blue-500 underline)" />
5)
6
7const mediaStyles = () => <div tw="sm:(w-4 mt-3) lg:(w-8 mt-6)" />
8
9const pseudoElementStyles = () => <div tw="before:(block w-10 h-10 bg-black)" />
10
11const stackedVariants = () => <div tw="sm:hover:(bg-black text-white)" />
12
13const groupsInGroups = () => <div tw="sm:(bg-black hover:(bg-white w-10))" />

🛎 Helpful suggestions for mistypings - Twin chimes in with class and variant values from your Tailwind config:

1✕ ml-1.25 was not found
2
3Try one of these classes:
4
5- ml-1.5 > 0.375rem
6- ml-1 > 0.25rem
7- ml-10 > 2.5rem

🖌️ Use the theme import to add values from your tailwind config

1import { css, theme } from 'twin.macro'
2
3const Input = () => <input css={css({ color: theme`colors.purple.500` })} />

💡 Works with the official tailwind vscode plugin - Avoid having to look up your classes with auto-completions straight from your Tailwind config - setup instructions →

💥 Add !important to any class with a trailing or leading bang!

1<div tw="hidden!" /> || <div tw="!hidden" />
2// ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
3<div css={{ "display": "none !important" }} />

Add !important to multiple classes with bracket groups:

1<div tw="(hidden ml-auto)!" />
2// ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
3<div css={{ "display": "none !important", "marginLeft": "auto !important" }} />

Special thanks

This project stemmed from babel-plugin-tailwind-components so a big shout out goes to Brad Cornes for the amazing work he produced. Styling with tailwind.macro has been such a pleasure.
