<self-position>
The <self-position> enumerated value data type is used by the justify-self and align-self properties, and the place-self shorthand, to align the box within its alignment container. It is also used by the justify-items and align-items properties, and the place-items shorthand, to specify default values for justify-self and align-self.
Syntax
<self-position> = center | start | end | self-start | self-end | flex-start | flex-end
Values
The following keyword values are represented by the <self-position> grammar term:
center-
Centers the alignment subject within its alignment container.
start-
Aligns the alignment subject flush with the alignment container's start edge.
end-
Aligns the alignment subject flush with the alignment container's end edge.
self-start-
Aligns the alignment subject flush with the edge of the alignment container corresponding to the alignment subject's start side.
self-end-
Aligns the alignment subject flush with the edge of the alignment container corresponding to the alignment subject's end side.
flex-start-
In flex layout, aligns the alignment subject flush with the edge of the alignment container corresponding to the flex container's main-start or cross-start side, as appropriate. It is identical to
startfor layout modes other than flex layout. flex-end-
In flex layout, aligns the alignment subject flush with the edge of the alignment container corresponding to the flex container's main-end or cross-end side, as appropriate. Identical to
endfor layout modes other than flex layout.
Note:
The left and right keywords are excluded from <self-position>, despite being valid positional alignment values for the justify-* properties (justify-content, justify-self, and justify-items), because they are not allowed in the align-* properties (align-content, align-self, and align-items). They are instead explicitly included in the justify-* properties' grammars.
