+
+// Flexbox Justify Content
+//
+// The 'justify-content' property aligns flex items along the main axis
+// of the current line of the flex container. This is done after any flexible
+// lengths and any auto margins have been resolved. Typically it helps distribute
+// extra free space leftover when either all the flex items on a line are
+// inflexible, or are flexible but have reached their maximum size. It also
+// exerts some control over the alignment of items when they overflow the line.
+//
+// Note: 'space-*' values not supported in older syntaxes.
+//
+// Values: flex-start | flex-end | center | space-between | space-around
+// Default: flex-start

+
+// Flexbox Align Items
+//
+// Flex items can be aligned in the cross axis of the current line of the
+// flex container, similar to 'justify-content' but in the perpendicular
+// direction. 'align-items' sets the default alignment for all of the flex
+// container's items, including anonymous flex items. 'align-self' allows
+// this default alignment to be overridden for individual flex items. (For
+// anonymous flex items, 'align-self' always matches the value of 'align-items'
+// on their associated flex container.)
+//
+// Values: flex-start | flex-end | center | baseline | stretch
+// Default: stretch
+//
+// http://w3.org/tr/css3-flexbox/#align-items-property

+//----------------------------------------------------------------------
+
+// Flexbox Align Content
+//
+// The 'align-content' property aligns a flex container's lines within the
