flex-direction

The flex-direction CSS property sets how flex items are placed in the flex container defining the main axis and the direction (normal or reversed).

Note that the values row and row-reverse are affected by the directionality of the flex 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.

Syntax

/* The direction text is laid out in a line */
flex-direction: row;

/* Like <row>, but reversed */
flex-direction: row-reverse;

/* The direction in which lines of text are stacked */
flex-direction: column;

/* Like <column>, but reversed */
flex-direction: column-reverse;

/* Global values */
flex-direction: inherit;
flex-direction: initial;
flex-direction: unset;

Values

The following values are accepted:

row
The flex container's main-axis is defined to be the same as the text direction. The main-start and main-end points are the same as the content direction.
row-reverse
Behaves the same as row but the main-start and main-end points are permuted.
column
The flex container's main-axis is the same as the block-axis. The main-start and main-end points are the same as the before and after points of the writing-mode.
column-reverse
Behaves the same as column but the main-start and main-end are permuted.

Accessibility concerns

Using the flex-direction property with values of row-reverse or column-reverse will create a disconnect between the visual presentation of content and DOM order. This will adversely affect users experiencing low vision navigating with the aid of assistive technology such as a screen reader. If the visual (CSS) order is important, then screen reader users will not have access to the correct reading order.
