As their names suggest, these axes form a hierarchical relationship, the main axis being superior to the cross axis.

It sets the height of the div to 100vh which stands for the whole viewport height. Row sets the display property to flex, justify-center centers it horizontally and items-center centers it vertically.īut in order to work, we need a height for the element.
