justify-content
The CSS justify-content
property defines how the browser distributes space between and around content items along the main-axis of a flex container, and the inline axis of a grid container.
The interactive example below demonstrates some of the values using Grid Layout.
Try it
The alignment is done after the lengths and auto margins are applied, meaning that, if in a Flexbox layout there is at least one flexible element, with flex-grow
different from 0
, it will have no effect as there won't be any available space.
Syntax
css
/* Positional alignment */
justify-content: center; /* Pack items around the center */
justify-content: start; /* Pack items from the start */
justify-content: end; /* Pack items from the end */
justify-content: flex-start; /* Pack flex items from the start */
justify-content: flex-end; /* Pack flex items from the end */
justify-content: left; /* Pack items from the left */
justify-content: right; /* Pack items from the right */
/* Baseline alignment */
/* justify-content does not take baseline values */
/* Normal alignment */
justify-content: normal;
/* Distributed alignment */
justify-content: space-between; /* Distribute items evenly
The first item is flush with the start,
the last is flush with the end */
justify-content: space-around; /* Distribute items evenly
Items have a half-size space
on either end */
justify-content: space-evenly; /* Distribute items evenly
Items have equal space around them */
justify-content: stretch; /* Distribute items evenly
Stretch 'auto'-sized items to fit
the container */
/* Overflow alignment */
justify-content: safe center;
justify-content: unsafe center;
/* Global values */
justify-content: inherit;
justify-content: initial;
justify-content: revert;
justify-content: revert-layer;
justify-content: unset;
Values
start
-
The items are packed flush to each other toward the start edge of the alignment container in the main axis.
end
-
The items are packed flush to each other toward the end edge of the alignment container in the main axis.
flex-start
-
The items are packed flush to each other toward the edge of the alignment container depending on the flex container's main-start side. This only applies to flex layout items. For items that are not children of a flex container, this value is treated like
start
. flex-end
-
The items are packed flush to each other toward the edge of the alignment container depending on the flex container's main-end side. This only applies to flex layout items. For items that are not children of a flex container, this value is treated like
end
. center
-
The items are packed flush to each other toward the center of the alignment container along the main axis.
left
-
The items are packed flush with each other toward the left edge of the alignment container. When the property's horizontal axis is not parallel with the inline axis, such as when
flex-direction: column;
is set, this value behaves likestart
. right
-
The items are packed flush to each other toward the right edge of the alignment container in the appropriate axis. If the property's axis is not parallel with the inline axis (in a grid container) or the main-axis (in a flexbox container), this value behaves like
start
. normal
-
Behaves as
stretch
, except in the case of multi-column containers with a non-auto
column-width
, in which case the columns take their specifiedcolumn-width
rather than stretching to fill the container. Asstretch
behaves asstart
in flex containers,normal
also behaves asstart
. space-between
-
The items are evenly distributed within the alignment container along the main axis. The spacing between each pair of adjacent items is the same. The first item is flush with the main-start edge, and the last item is flush with the main-end edge.
space-around
-
The items are evenly distributed within the alignment container along the main axis. The spacing between each pair of adjacent items is the same. The empty space before the first and after the last item equals half of the space between each pair of adjacent items.
space-evenly
-
The items are evenly distributed within the alignment container along the main axis. The spacing between each pair of adjacent items, the main-start edge and the first item, and the main-end edge and the last item, are all exactly the same.
stretch
-
If the combined size of the items along the main axis is less than the size of the alignment container, any
auto
-sized items have their size increased equally (not proportionally), while still respecting the constraints imposed bymax-height
/max-width
(or equivalent functionality), so that the combined size exactly fills the alignment container along the main axis.Note: While
stretch
is supported by flexible boxes (flexbox), when applied on a flexbox, as stretching is controlled byflex
,stretch
behaves asstart
. safe
-
If the item overflows the alignment container, then the item is aligned as if the alignment mode is
start
. The desired alignment will not be implemented. unsafe
-
Even if the item overflows the alignment container, the desired alignment will be implemented. Unlike
safe
, which will ignore the desired alignment in favor of preventing overflow.
