-In the following example the red, yellow and the green views are all children in the container view that has `flex: 1` set. The red view uses `flex: 1` , the yellow view uses `flex: 2` and the green view uses `flex: 3` . **1+2+3 = 6** which means that the red view will get `1/6` of the space, the yellow `2/6` of the space and the green `3/6` of the space.

 #### Flex Direction
 
 [`flexDirection`](https://facebook.github.io/react-native/docs/layout-props#flexdirection) controls the direction in which the children of a node are laid out. This is also referred to as the _main axis_. The cross axis is the axis perpendicular to the main axis, or the axis which the wrapping lines are laid out in.

 ### Flex Basis, Grow, and Shrink
 
 - [`flexGrow`](https://facebook.github.io/react-native/docs/layout-props#flexgrow) describes how any space within a container should be distributed among its children along the main axis. After laying out its children, a container will distribute any remaining space according to the flex grow values specified by its children.
 
-  flexGrow accepts any floating point value >= 0, with 0 being the default value. A container will distribute any remaining space among its children weighted by the child’s flex grow value.
+  `flexGrow` accepts any floating point value >= 0, with 0 being the default value. A container will distribute any remaining space among its children weighted by the children’s `flexGrow` values.
 
-- [`flexShrink`](https://facebook.github.io/react-native/docs/layout-props#flexshrink) describes how to shrink children along the main axis in the case that the total size of the children overflow the size of the container on the main axis. Flex shrink is very similar to flex grow and can be thought of in the same way if any overflowing size is considered to be negative remaining space. These two properties also work well together by allowing children to grow and shrink as needed.

-- [`flexBasis`](https://facebook.github.io/react-native/docs/layout-props#flexbasis) is an axis-independent way of providing the default size of an item along the main axis. Setting the flex basis of a child is similar to setting the `width` of that child if its parent is a container with `flexDirection: row` or setting the `height` of a child if its parent is a container with `flexDirection: column`. The flex basis of an item is the default size of that item, the size of the item before any flex grow and flex shrink calculations are performed.

+Both `width` and `height` can take the following values:

+- `auto` (**default value**) React Native calculates the width/height for the element based on its content, whether that is other children, text, or an image.
 
 - `pixels` Defines the width/height in absolute pixels. Depending on other styles set on the component, this may or may not be the final dimension of the node.
 
-- `percentage` Defines the width or height in percentage of its parent's width or height respectively.
+- `percentage` Defines the width or height in percentage of its parent's width or height, respectively.
 
 ### Absolute & Relative Layout
 
 The `position` type of an element defines how it is positioned within its parent.
 
-`relative` (**default value**) By default an element is positioned relatively. This means an element is positioned according to the normal flow of the layout, and then offset relative to that position based on the values of `top`, `right`, `bottom`, and `left`. The offset does not affect the position of any sibling or parent elements.
