Box is the most abstract component on top of which most other primitive components are built. By default it renders a div element.


The Box component is useful for a variety of cases:

  • Create responsive layouts
  • Implement basic styles within the constraints of the theme
  • Compose new components and support overriding the underlying element using the as prop


The padding keys allow targeting each side as well as the x-axis and y-axis.

  • padding
  • paddingTop
  • paddingRight
  • paddingBottom
  • paddingLeft
  • paddingX padding-left and padding-right
  • paddingY padding-top and padding-bottom

The margin keys allow targeting each side as well as the x-axis and y-axis.

  • margin
  • marginTop
  • marginRight
  • marginBottom
  • marginLeft
  • marginX margin-left and margin-right
  • marginY margin-top and margin-bottom


The rounding keys allow targeting each box side.

  • rounding border-radius
  • roundingBottom border-bottom-left-radius and border-bottom-right-radius
  • roundingLeft border-bottom-left-radius and border-top-left-radius
  • roundingRight border-bottom-right-radius and border-top-right-radius
  • roundingTop border-bottom-left-radius and border-bottom-right-radius

The rounding values don't follow the traditional t-shirt sizes.

  • small
  • medium

Text Align

Align the text within a box:

  • textAlign text-align CSS property

The available values match the CSS property:

  • left
  • right
  • center
  • justify
  • start
  • end
centered text


Set the height of a box:

  • height height CSS property
100px tall


Set the width of a box:

  • width width CSS property
200px wide


Mix and match style properties to achieve the desired aesthetic.


Responsive Props

Instead of manually managing media queries and adding nested style objects throughout a code base, we offer a convenient shorthand syntax for adding responsive styles with a mobile-first approach.

Each of the above style props accepts a value or array of values. To skip certain breakpoints, you can pass null to any position in the array to avoid generating unnecessary CSS.

While this approach has been widely adopted with great success, much like any new idea, it can seem odd or off-putting at first. We recommend giving it a chance.
