// Flexbox Containers
|

//
|
||||
// The 'flex' value causes an element to generate a block-level flex
|
||||
// container box.
|

//
|
||||
// Display: flex
|
||||
//
|
||||
// http://w3.org/tr/css3-flexbox/#flex-containers

// Flexbox 'Flex' (shorthand)
|
||||
//
|
||||
// The 'flex' property specifies the components of a flexible length: the
|
||||
// flex grow factor and flex shrink factor, and the flex basis. When an
|
||||
// element is a flex item, 'flex' is consulted instead of the main size
|
||||
// property to determine the main size of the element. If an element is
|
||||
// not a flex item, 'flex' has no effect.
|
||||
//
|
||||
// Values: <flex-basis>
|
||||
// Default: 1

||||
//
|
||||
// http://w3.org/tr/css3-flexbox/#flex-property

// Flexbox Direction
|
||||
//
|
||||
// The 'flex-direction' property specifies how flex items are placed in
|
||||
// the flex container, by setting the direction of the flex container's
|
||||
// main axis. This determines the direction that flex items are laid out in.
|
||||
//
|
||||
// Values: row | row-reverse | column | column-reverse

|

//
|

// The 'flex-wrap' property controls whether the flex container is single-line

// or multi-line, and the direction of the cross-axis, which determines
|
||||
// the direction new lines are stacked in.
|

// Flexbox Flow (shorthand)
|

//
|

// The 'flex-flow' property is a shorthand for setting the 'flex-direction'

|
||||
// main and cross axes.
|

//
|

// The 'justify-content' property aligns flex items along the main axis

//
|
