flex-direction
CSS flex-direction Property
The flex-direction property specifies the main axis of a flex container and sets the order of flex items. It is one of the CSS3 properties. This property is a part of the Flexible Box Layout module.
Flex items can be displayed:
horizontally from left to right (flex-direction:row) or right to left (flex-direction:row-reverse)
vertically from top to bottom (flex-direction:column) or from bottom to top (flex-direction)
If there are no flexible items, the flex-direction property has no effect.
