## Flex Basis, Grow, and Shrink
|
||
|
||
**FLEX GROW** 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.
|
||
|
||
Flex grow 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.
|
||
|
||

|
||
|
||
**FLEX SHRINK** 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.
|
||
|
||
Flex shrink accepts any floating point value >= 0, with 1 being the default value.
|
||
A container will shrink its children weighted by the child’s flex shrink value.
|
||
|
||
<controls prop="flexShrink"></controls>
|
||
|
||
**FLEX BASIS** 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
|
||
efault size of that item, the size of the item before any flex grow and flex shrink
|
||
calculations are performed.
