Concepts

Patterns

Patterns are layout primitives can be used to create robust and responsive layouts with ease. Panda comes with predefined patterns like stack, hstack, vstack, wrap, etc. These patterns can be used as functions or JSX elements.

Predefined Patterns

Container

The Container pattern is used to create a container with a max-width and center the content.

By default, the container sets the following properties:

• maxWidth: 8xl
• marginX: auto
• position: relative
• paddingX: { base: 4, md: 6, lg: 8 }

import { container } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={container()}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

Stack

The Stack pattern is a layout primitive that can be used to create a vertical or horizontal stack of elements.

The stack function accepts the following properties:

• direction: The flex direction of the stack. Can be either vertical or horizontal.
• gap: The gap between the elements in the stack.
• align: An alias for the css align-items property.
• justify: An alias for the css justify-content property.

import { stack } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={stack({ gap: '6', padding: '4' })}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

HStack

The HStack pattern is a wrapper around the stack pattern that sets the direction property to horizontal, and centers the elements vertically.

import { hstack } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={hstack({ gap: '6' })}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

VStack

The VStack pattern is a wrapper around the stack pattern that sets the direction property to vertical, and centers the elements horizontally.

import { vstack } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={vstack({ gap: '6' })}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

Wrap

The Wrap pattern is used to add space between elements and wraps automatically if there isn't enough space.

The wrap function accepts the following properties:

• gap: The gap between the elements in the stack.
• columnGap: The gap between the elements in the stack horizontally.
• rowGap: The gap between the elements in the stack vertically.
• align: An alias for the css align-items property.
• justify: An alias for the css justify-content property.

import { wrap } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={wrap({ gap: '6' })}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

Aspect Ratio

The Aspect Ratio pattern is used to create a container with a fixed aspect ratio. It is used when displaying images, maps, videos and other media.

The aspectRatio function accepts the following properties:

• ratio: The aspect ratio of the container. Can be a number or a string.

function App() {
  return (
    <div className={aspectRatio({ ratio: 16 / 9 })}>
      <iframe
        src="https://www.google.com/maps/embed?pb=!1m18!1m1"
        title="Google map"
        frameBorder="0"
      />
    </div>
  )
}

Flex

The Flex pattern is used to create a flex container and provides some shortcuts for the flex property.

The flex function accepts the following properties:

• direction: The flex direction of the container. Can be row, column, row-reverse or column-reverse.
• wrap: Whether to wrap the flex items. The value is a boolean.
• align: An alias for the css align-items property.
• justify: An alias for the css justify-content property.
• basis: An alias for the css flex-basis property.
• grow: An alias for the css flex-grow property.
• shrink: An alias for the css flex-shrink property.

import { flex } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={flex({ direction: 'row', align: 'center' })}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

Center

The Center pattern is used to center the content of a container.

The center function accepts the following properties:

• inline: Whether to use inline-flex or flex for the container. The value is a boolean.

import { center } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={center({ bg: 'red.200' })}>
      <Icon />
    </div>
  )
}

Float

The Float pattern is used to anchor an element to the top, bottom, left or right of the container.

The float function accepts the following properties:

• placement: The placement of the element. Can be top-start, top, top-end, bottom-start, bottom, bottom-end, left-start, left, left-end, right-start, right or right-end.
• offset: The offset of the element from the edge of the container. Can be a number or a string.
• offsetX: Same as offset, but only for the horizontal axis.
• offsetY: Same as offset, but only for the vertical axis.

function App() {
  return (
    <div className={css({ position: 'relative' })}>
      <div className={float({ placement: 'top-start' })}>3</div>
    </div>
  )
}

Grid

The Grid pattern is used to create a grid layout.

The grid function accepts the following properties:

• columns: The number of columns in the grid.
• gap: The gap between the elements in the stack.
• columnGap: The gap between the elements in the stack horizontally.
• rowGap: The gap between the elements in the stack vertically.
• minChildWidth: The minimum width of the child elements before wrapping.

import { grid } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={grid({ columns: 3, gap: '6' })}>
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

Grid Item

The Grid Item pattern is used to style the children of a grid container.

The gridItem function accepts the following properties:

• colSpan: The number of columns the item spans.
• rowSpan: The number of rows the item spans.
• rowStart: The row the item starts at.
• rowEnd: The row the item ends at.
• colStart: The column the item starts at.
• colEnd: The column the item ends at.

import { grid, gridItem } from '../styled-system/patterns'
 
function App() {
  return (
    <div className={grid({ columns: 3, gap: '6' })}>
      <div className={gridItem({ colSpan: 2 })}>First</div>
      <div>Second</div>
      <div>Third</div>
    </div>
  )
}

Divider

The Divider pattern is used to create a horizontal or vertical divider.

The divider function accepts the following properties:

• orientation: The orientation of the divider. Can be horizontal or vertical.
• thickness: The thickness of the divider. Can be a sizing token, or arbitrary value.
• color: The color of the divider. Can be a color token, or arbitrary value.

import { divider } from '../styled-system/patterns'
 
function App() {
  return (
    <div classname={stack()}>
      <button>First</button>
      <div className={divider({ orientation: 'horizontal' })} />
      <button>Second</button>
    </div>
  )
}

Circle

The Circle pattern is used to create a circle.

The circle function accepts the following properties:

• size: The size of the circle. Can be a sizing token, or arbitrary value.

import { circle } from '../styled-system/patterns'
 
function App() {
  return <div className={circle({ size: '12', bg: 'red.300' })} />
}

Square

The Square pattern is used to create a square with equal width and height.

The square function accepts the following properties:

• size: The size of the square. Can be a sizing token, or arbitrary value.

import { square } from '../styled-system/patterns'
 
function App() {
  return <div className={square({ size: '12', bg: 'red.300' })} />
}

Usage with JSX

To use the pattern in JSX, you need to set the jsxFramework property in the config. When this is set, Panda will emit files for JSX elements based on the framework.

Every pattern can be used as a JSX element and imported from the /jsx entrypoint. The pattern name is the same as the function name, but in PascalCase.

import { VStack, Center } from '../styled-system/jsx'
 
function App() {
  return (
    <VStack gap="6" mt="4">
      <div>First</div>
      <div>Second</div>
      <div>Third</div>
      <Center>4</Center>
    </VStack>
  )
}
