CSS flex-direction Property

Description

The flex-direction property allows you to specify the direction in accordance with which the flex elements are located inside the flex container. The direction of flex elements is formed based on the position of two axes: the main axis of the flex container and its transverse axis , which is always located perpendicular to the main . The main axis in the ltr direction (the global HTML dir attribute, or the CSS direction property with ltr value) is located from left to right, and the transverse axis is from top to bottom (this is the default value), for the rtl value it is mirrored accordingly.
