Changelog

[0.37.0] - 2024-04-01

Fixed

• Fix className collisions between utilities by using unique class names per property in the default preset.

• Fix a bug where some styles would be grouped together in the same rule, even if they were not related to each other.

Internal details

This was caused by an object reference being re-used while setting a property deeply in the hashes decoding process, leading to the mutation of a previous style object with additional properties.

Added

• Add missing typings for CSS vars in properties bound to utilities (and that are not part of the list affected by strictPropertyValues)
• Allow multiple importMap (or multiple single import entrypoints if using the object format).

It can be useful to use a component library's styled-system while also using your own styled-system in your app.

import { defineConfig } from '@pandacss/dev'

export default defineConfig({
  importMap: ['@acme/styled-system', '@ui-lib/styled-system', 'styled-system'],
})

Now you can use any of the @acme/styled-system, @ui-lib/styled-system and styled-system import sources:

import { css } from '@acme/css'
import { css as uiCss } from '@ui-lib/styled-system/css'
import { css as appCss } from '@ui-lib/styled-system/css'

• Spacing Utilities: Add new spaceX and spaceY utilities for applying margin between elements. Especially useful when applying negative margin to child elements.

<div className={flex({ spaceX: '-1' })}>
  <div className={circle({ size: '5', bg: 'red' })} />
  <div className={circle({ size: '5', bg: 'pink' })} />
</div>

• Added new _starting condition to support the new @starting-style at-rule. Learn more here

• Gradient Position: Add new gradientFromPosition and gradientToPosition utilities for controlling the position of the gradient color stops.

<div
  className={css({
    bgGradient: 'to-r',
    // from
    gradientFrom: 'red',
    gradientFromPosition: 'top left',
    // to
    gradientTo: 'blue',
    gradientToPosition: 'bottom right',
  })}
/>

Changed

• Color Mode Selectors: Changed the default selectors for _light and _dark to target parent elements. This ensures consistent behavior with using these conditions to style pseudo elements (like ::before and ::after).

const conditions = {
-  _dark: '&.dark, .dark &',
+  _dark: '.dark &',
-  _light: '&.light, .light &',
+  _light: '.light &',
}

• Changed divideX and divideY now maps to the borderWidths token group.
