Props
marginRight
marginRight works like margin-right in CSS. See http://www.w3schools.com/cssref/pr_margin-right.asp for more details.
| Type | Required |
|---|---|
| ReactPropTypes.number | No |
alignItems
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, except the default value is stretch instead of flex-start. See https://css-tricks.com/almanac/properties/a/align-items/ for more detail.
| Type | Required |
|---|
| ReactPropTypes.oneOf([ 'flex-start', 'flex-end', 'center', 'stretch' ]) | No |
borderBottomWidth
borderBottomWidth works like border-bottom-width in CSS. See http://www.w3schools.com/cssref/pr_border-bottom_width.asp for more details.
| Type | Required |
|---|---|
| ReactPropTypes.number | No |
borderLeftWidth
borderLeftWidth works like border-left-width in CSS. See http://www.w3schools.com/cssref/pr_border-bottom_width.asp for more details.
| Type | Required |
|---|---|
| ReactPropTypes.number | No |
borderRightWidth
borderRightWidth works like border-right-width in CSS. See http://www.w3schools.com/cssref/pr_border-right_width.asp for more details.
| Type | Required |
|---|---|
| ReactPropTypes.number | No |
borderTopWidth

borderWidth
borderWidth works like border-width in CSS. See http://www.w3schools.com/cssref/pr_border-width.asp for more details.
| Type | Required |
|---|---|
| ReactPropTypes.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 logical pixel units, rather than percents, ems, or any of that.
See https://developer.mozilla.org/en-US/docs/Web/CSS/bottom for more details of how top affects layout.
| Type | Required |
|---|---|
| ReactPropTypes.number | 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 css-layout library at https://github.com/facebook/css-layout .
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.
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.
| Type | Required |
|---|---|
| ReactPropTypes.number | 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://css-tricks.com/almanac/properties/f/flex-direction/ for more detail.
| Type | Required |
|---|
| ReactPropTypes.oneOf([ 'row', 'row-reverse', 'column', 'column-reverse' ]) | 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. See https://css-tricks.com/almanac/properties/f/flex-wrap/ for more detail.
| Type | Required |
|---|
| ReactPropTypes.oneOf([ 'wrap', 'nowrap' ]) | No |
height
height sets the height of this component.
It works similarly to height in CSS, but in React Native you must use logical pixel units, rather than percents, ems, or any of that. See http://www.w3schools.com/cssref/pr_dim_width.asp for more details.
| Type | Required |
|---|---|
| ReactPropTypes.number | No |
justifyContent

| Type | Required |
|---|
| ReactPropTypes.oneOf([ 'flex-start', 'flex-end', 'center', 'space-between', 'space-around' ]) | No |

| Type | Required |
|---|---|

position
position in React Native is similar to regular CSS, but everything is set to relative by default, so absolute positioning is always just 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, just don't use styles for that. Use the component tree.
See https://github.com/facebook/css-layout for more details on how position differs between React Native and CSS.
| Type | Required |
|---|
| ReactPropTypes.oneOf([ 'absolute', 'relative' ]) | No |
right
right is the number of logical pixels to offset the right edge of this component.
It works similarly to right in CSS, but in React Native you must use logical pixel units, rather than percents, ems, or any of that.
See https://developer.mozilla.org/en-US/docs/Web/CSS/right for more details of how right affects layout.
| Type | Required |
|---|---|
| ReactPropTypes.number | 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 logical pixel units, rather than percents, ems, or any of that.
See https://developer.mozilla.org/en-US/docs/Web/CSS/top for more details of how top affects layout.
| Type | Required |
|---|---|
| ReactPropTypes.number | 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 detail.
On iOS, zIndex may require Views to be siblings of each other for it to work as expected.
