Use responsive-friendly custom flex classes to build nested layouts with fixed and fluid columns. The classes are named using the format flex-{property} for xs and flex-{breakpoint}-{property} for sm, md, lg, xl, and xxl.
Where property is one of:
  • root - to define the root node of the flex layout(usually it's used when the layout is placed as a direct child of the body element in order to fully occupy the window height)
  • column-auto - to set a flex item with auto height
  • column-fluid - to set a flex item with fluid height
  • row-auto - to set a flex item with auto width
  • row-fluid - to set a flex item with fluid width
  • center - to set a flex item's content vertically and horizontally centered
  • start - to set a flex item's content alignments to start
  • end - to set a flex item's content alignments to end
