Customize how Panda works via the panda.config.ts file in your project.

import { defineConfig } from '@pandacss/dev'
 
export default defineConfig({
  // your configuration options here...
})

Output css options

presets

Type: string[]

Default: ['@pandacss/preset-base', '@pandacss/preset-panda']

The set of reusable and shareable configuration presets.

By default, any preset you add will be smartly merged with the default configuration, with your own configuration acting as a set of overrides and extensions.

{
  "presets": ["@pandacss/preset-base", "@pandacss/preset-panda"]
}

eject

Type: boolean

Default: false

Whether to opt-out of the defaults config presets: [@pandacss/preset-base, @pandacss/preset-panda]

{
  "eject": true
}

preflight

Type: boolean | { scope: string; }

Default: true

Whether to enable css reset styles.

Disable preflight:

{
  "preflight": false
}

You can also scope the preflight; Especially useful for being able to scope the CSS reset to only a part of the app for some reason.

Enable preflight and customize the scope:

{
  "preflight": { "scope": ".extension" }
}

The resulting reset css would look like this:

.extension button,
.extension select {
  text-transform: none;
}
 
.extension table {
  text-indent: 0;
  border-color: inherit;
  border-collapse: collapse;
}

emitTokensOnly

Type: boolean

Default: false

Whether to only emit the tokens directory

{
  "emitTokensOnly": false
}

prefix

Type: string

The namespace prefix for the generated css classes and css variables.

Ex: when using a prefix of panda-

{
  "prefix": "panda"
}

import { css } from '../styled-system/css'
 
const App = () => {
  return <div className={css({ color: 'blue.500' })} />
}

would result in:

.panda-text_blue\.500 {
  color: var(--panda-colors-blue-500);
}

layers

Type: Partial<Layer>

Cascade layers used in generated css.

Ex: when customizing the utilities layer

{
  "layers": {
    "utilities": "panda_utilities"
  }
}

import { css } from '../styled-system/css'
 
const App = () => {
  return <div className={css({ color: 'blue.500' })} />
}

would result in:

@layer panda_utilities {
  .text_blue\.500 {
    color: var(--colors-blue-500);
  }
}

You should update the layer in your root css also.

separator

Type: '_' | '=' | '-'

Default: '_'

The separator for the generated css classes.

{
  "separator": "_"
}

Using a = with:

import { css } from '../styled-system/css'
 
const App = () => {
  return <div className={css({ color: 'blue.500' })} />
}

would result in:

.text\=blue\.500 {
  color: var(--colors-blue-500);
}

optimize

Type: boolean

Default: true

Whether to optimize the generated css. This can be set to false to boost build times during development.

{
  "optimize": true
}

minify

Type: boolean

Default: false

Whether to minify the generated css. This can be set to true to reduce the size of the generated css.

{
  "minify": false
}

hash

Type: boolean | { cssVar: boolean; className: boolean }

Default: false

Whether to hash the generated class names / css variables. This is useful if want to shorten the class names or css variables.

Hash the class names and css variables:

{
  "hash": true
}

This

import { css } from '../styled-system/css'
 
const App = () => {
  return <div className={css({ color: 'blue.500' })} />
}

would result in something that looks like:

.dOFUTE {
  color: var(--cgpxvS);
}

You can also hash them individually.

E.g. only hash the css variables:

{
  "hash": { "cssVar": true, "className": false }
}

Then the result looks like this:

.text_blue\.500 {
  color: var(--cgpxvS);
}

Now only hash the class names:

{
  "hash": { "cssVar": false, "className": true }
}

Then the result looks like this:

.dOFUTE {
  color: var(--colors-blue-500);
}
