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).
The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.
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.
