Props

`alignContent`

alignContent controls how rows align in the cross direction, overriding the alignContent of the parent. See https://developer.mozilla.org/en-US/docs/Web/CSS/align-content for more details.

Type	Required
enum('flex-start', 'flex-end', 'center', 'stretch', 'space-between', 'space-around')	No

alignItems aligns children in the cross direction. For example, if children are flowing vertically, alignItems controls how they align horizontally. It works like align-items in CSS (default: stretch). See https://developer.mozilla.org/en-US/docs/Web/CSS/align-items for more details.

Type	Required
enum('flex-start', 'flex-end', 'center', 'stretch', 'baseline')	No

`alignSelf`

alignSelf controls how a child aligns in the cross direction, overriding the alignItems of the parent. It works like align-self in CSS (default: auto). See https://developer.mozilla.org/en-US/docs/Web/CSS/align-self for more details.

Type	Required
enum('auto', 'flex-start', 'flex-end', 'center', 'stretch', 'baseline')	No

`aspectRatio`

Aspect ratio controls the size of the undefined dimension of a node. Aspect ratio is a non-standard property only available in React Native and not CSS.

On a node with a set width/height aspect ratio controls the size of the unset dimension
On a node with a set flex basis aspect ratio controls the size of the node in the cross axis if unset
On a node with a measure function aspect ratio works as though the measure function measures the flex basis
On a node with flex grow/shrink aspect ratio controls the size of the node in the cross axis if unset
Aspect ratio takes min/max dimensions into account

Type	Required
number	No

`borderBottomWidth`

borderBottomWidth works like border-bottom-width in CSS. See https://developer.mozilla.org/en-US/docs/Web/CSS/border-bottom-width for more details.

Type	Required

`borderEndWidth`

When direction is ltr, borderEndWidth is equivalent to borderRightWidth. When direction is rtl, borderEndWidth is equivalent to borderLeftWidth.

Type	Required
number	No

`borderLeftWidth`

borderLeftWidth works like border-left-width in CSS. See https://developer.mozilla.org/en-US/docs/Web/CSS/border-left-width for more details.

Type	Required
number	No

borderRightWidth works like border-right-width in CSS. See https://developer.mozilla.org/en-US/docs/Web/CSS/border-right-width for more details.

Type	Required
number	No

`borderStartWidth`

When direction is ltr, borderStartWidth is equivalent to borderLeftWidth. When direction is rtl, borderStartWidth is equivalent to borderRightWidth.

Type	Required
number	No

Type	Required
number	No

`borderWidth`

borderWidth works like border-width in CSS. See https://developer.mozilla.org/en-US/docs/Web/CSS/border-width for more details.

Type	Required
number	No

`bottom`

bottom is the number of logical pixels to offset the bottom edge of this component.

It works similarly to bottom in CSS, but in React Native you must use points or percentages. Ems and other units are not supported.

See https://developer.mozilla.org/en-US/docs/Web/CSS/bottom for more details of how bottom affects layout.

Type	Required
number, string	No

`direction`

direction specifies the directional flow of the user interface. The default is inherit, except for root node which will have value based on the current locale. See https://yogalayout.com/docs/layout-direction for more details.

Type	Required	Platform
enum('inherit', 'ltr', 'rtl')	No	iOS

`display`

display sets the display type of this component.

It works similarly to display in CSS, but only support 'flex' and 'none'. 'flex' is the default.

Type	Required
enum('none', 'flex')	No

`end`

When the direction is ltr, end is equivalent to right. When the direction is rtl, end is equivalent to left.

This style takes precedence over the left and right styles.

Type	Required
number, string	No

`flex`

In React Native flex does not work the same way that it does in CSS. flex is a number rather than a string, and it works according to the Yoga.

When flex is a positive number, it makes the component flexible and it will be sized proportional to its flex value. So a component with flex set to 2 will take twice the space as a component with flex set to 1. flex: <positive number> equates to flexGrow: <positive number>, flexShrink: 1, flexBasis: 0.

When flex is 0, the component is sized according to width and height and it is inflexible.

When flex is -1, the component is normally sized according width and height. However, if there's not enough space, the component will shrink to its minWidth and minHeight.

flexGrow, flexShrink, and flexBasis work the same as in CSS.

Type	Required
number	No

`flexBasis`

Type	Required
number, string	No

`flexDirection`

flexDirection controls which directions children of a container go. row goes left to right, column goes top to bottom, and you may be able to guess what the other two do. It works like flex-direction in CSS, except the default is column. See https://developer.mozilla.org/en-US/docs/Web/CSS/flex-direction for more details.

Type	Required

`flexGrow`

Type	Required
number	No

`flexShrink`

Type	Required
number	No

`flexWrap`

flexWrap controls whether children can wrap around after they hit the end of a flex container. It works like flex-wrap in CSS (default: nowrap). See https://developer.mozilla.org/en-US/docs/Web/CSS/flex-wrap for more details. Note it does not work anymore with alignItems: stretch (the default), so you may want to use alignItems: flex-start for example (breaking change details: https://github.com/facebook/react-native/releases/tag/v0.28.0).

Type	Required
enum('wrap', 'nowrap')	No

`height`

height sets the height of this component.

Type	Required
number, string	No

`justifyContent`

justifyContent aligns children in the main direction. For example, if children are flowing vertically, justifyContent controls how they align vertically. It works like justify-content in CSS (default: flex-start). See https://developer.mozilla.org/en-US/docs/Web/CSS/justify-content for more details.

Type	Required
enum('flex-start', 'flex-end', 'center', 'space-between', 'space-around', 'space-evenly')	No

`left`

left is the number of logical pixels to offset the left edge of this component.

`paddingVertical`

Setting paddingVertical is like setting both of paddingTop and paddingBottom.

Type	Required
number, string	No

`position`

position in React Native is similar to regular CSS, but everything is set to relative by default, so absolute positioning is always relative to the parent.

If you want to position a child using specific numbers of logical pixels relative to its parent, set the child to have absolute position.

If you want to position a child relative to something that is not its parent, don't use styles for that. Use the component tree.

See https://github.com/facebook/yoga for more details on how position differs between React Native and CSS.

Type	Required
enum('absolute', 'relative')	No

`right`

right is the number of logical pixels to offset the right edge of this component.

This style takes precedence over the left, right, and end styles.

Type	Required
number, string	No

`top`

top is the number of logical pixels to offset the top edge of this component.

It works similarly to top in CSS, but in React Native you must use points or percentages. Ems and other units are not supported.

width sets the width of this component.

It works similarly to width in CSS, but in React Native you must use points or percentages. Ems and other units are not supported. See https://developer.mozilla.org/en-US/docs/Web/CSS/width for more details.

Type	Required
number, string	No

`zIndex`

zIndex controls which components display on top of others. Normally, you don't use zIndex. Components render according to their order in the document tree, so later components draw over earlier ones. zIndex may be useful if you have animations or custom modal interfaces where you don't want this behavior.

It works like the CSS z-index property - components with a larger zIndex will render on top. Think of the z-direction like it's pointing from the phone into your eyeball. See https://developer.mozilla.org/en-US/docs/Web/CSS/z-index for more details.

On iOS, zIndex may require Views to be siblings of each other for it to work as expected.

Type	Required
number	No
