The linear-direction CSS property sets how linear items are placed in the linear container defining the main axis and the direction.
Note that the values row, row-reverse are affected by the directionality of the linear container. If its dir attribute is ltr, row represents the horizontal axis oriented from the left to the right, and row-reverse from the right to the left; if the dir attribute is rtl, row represents the axis oriented from the right to the left, and row-reverse from the left to the right.
