The CSS justify-items
property defines the default justify-self
for all items of the box, given them the default way of justifying each box along the appropriate axis.
/* Basic keywords */ justify-items: auto; justify-items: normal; justify-items: stretch; /* Positional alignment */ justify-items: center; /* Pack items around the center */ justify-items: start; /* Pack items from the start */ justify-items: end; /* Pack items from the end */ justify-items: flex-start; /* Pack flex items from the start */ justify-items: flex-end; /* Pack flex items from the end */ justify-items: self-start; justify-items: self-end; justify-items: left; /* Pack items from the left */ justify-items: right; /* Pack items from the right */ /* Baseline alignment */ justify-items: baseline; justify-items: first baseline; justify-items: last baseline; /* Overflow alignment (for positional alignment only) */ justify-items: safe center; justify-items: unsafe center; /* Legacy alignment */ justify-items: legacy right; justify-items: legacy left; justify-items: legacy center; /* Global values */ justify-items: inherit; justify-items: initial; justify-items: unset;
Syntax
This property can take one of four different forms:
- Basic keywords: one of the keyword values
normal
,auto
, orstretch
. - Baseline alignment: the
baseline
keyword, plus optionally one offirst
orlast
. - Positional alignment: one of:
center
,start
,end
,flex-start
,flex-end
,self-start
,self-end
,left
, orright
. Plus optionallysafe
orunsafe
. - Legacy alignment: the
legacy
keyword, followed by one ofleft
orright
.
Values
auto
- The value used is the value of the
justiy-items
property of the parents box, unless the box has no parent, or is absolutely positioned, in these cases,auto
representsnormal
. normal
- The effect of this keyword is dependent of the layout mode we are in:
- In block-level layouts, the keyword is a synonym of
start
. - In absolutely-positioned layouts, the keyword behaved like
start
on replaced absolutely-positioned boxes, and asstretch
on all other absolutely-positioned boxes. - In table cell layouts, this keyword has no meaning as this property is ignored.
- In flexbox layouts, this keyword has no meaning as this property is ignored.
- In grid layouts, this keyword leads to a behavior similar to the one of
stretch
, except for boxes with an aspect ratio or an intrinsic sizes where it behaves likestart
.
- In block-level layouts, the keyword is a synonym of
start
- The item is packed flush to each other toward the start edge of the alignment container in the appropriate axis.
end
- The item is packed flush to each other toward the end edge of the alignment container in the appropriate axis.
flex-start
- The item ispacked flush to each other toward the edge of the alignment container depending on the flex container's main-start or cross-start side.
This only applies to flex layout items. For items that are not children of a flex container, this value is treated likestart
. flex-end
- The item is packed flush to each other toward the edge of the alignment container depending on the flex container's main-end or cross-end side.
This only applies to flex layout items. For items that are not children of a flex container, this value is treated likeend
. self-start
- The item is packed flush to the edge of the alignment container of the start side of the item, in the appropriate axis.
self-end
- The item is packed flush to the edge of the alignment container of the end side of the item, in the appropriate axis.
center
- The items are packed flush to each other toward the center of the of the alignment container.
left
- The items are packed flush to each other toward the left edge of the alignment container. If the property’s axis is not parallel with the inline axis, this value behaves like
start
. 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, this value behaves like
start
. baseline
first baseline
last baseline
- Specifies participation in first- or last-baseline alignment: aligns the alignment baseline of the box’s first or last baseline set with the corresponding baseline in the shared first or last baseline set of all the boxes in its baseline-sharing group.
The fallback alignment forfirst baseline
isstart
, the one forlast baseline
isend
. stretch
- If the combined size of the items 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. safe
- If the size of the item overflows the alignment container, the item is instead aligned as if the alignment mode were
start
. unsafe
- Regardless of the relative sizes of the item and alignment container, the given alignment value is honored.
legacy
- Makes the value inherited by the box descendants. Note that if a descendant has a
justify-self: auto
value, thelegacy
keyword is not considered by the descend, only theleft
,right
, orcenter
value associated to it.
