flex-direction
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.
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).
Try it
flex-direction: row;
flex-direction: row-reverse;
flex-direction: column;
flex-direction: column-reverse;
<section class="default-example" id="default-example">
<div class="transition-all" id="example-element">
<div>Item One</div>
<div>Item Two</div>
<div>Item Three</div>
</div>
</section>
#example-element {
border: 1px solid #c5c5c5;
width: 80%;
display: flex;
}
#example-element > div {
background-color: rgb(0 0 255 / 0.2);
border: 3px solid blue;
width: 60px;
margin: 10px;
}
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: revert;
flex-direction: revert-layer;
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
rowbut the main-start and main-end points are opposite to the content direction. 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
columnbut the main-start and main-end are opposite to the content direction.
Accessibility
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.
