    align-self

    This article is in need of a technical review.

    Summary

    The align-self CSS property aligns flex items of the current flex line overriding the align-items value. If any of the flex item's cross-axis margin is set to auto, then align-self is ignored.

    • Initial value auto
    • Applies to flex items, including in-flow pseudo-elements
    • Inherited no
    • Media visual
    • Computed value auto computes to parent's align-items; otherwise as specified
    • Animatable no
    • Canonical order the unique non-ambiguous order defined by the formal grammar

    See Using CSS flexible boxes for more properties and information.

    Syntax

    align-self: auto
    align-self: flex-start

    Values

    auto
    Computes to parent's align-items value or stretch if the element has no parent.
    flex-start
    The cross-start margin edge of the flex item is flushed with the cross-start edge of the line.
    flex-end
    The cross-end margin edge of the flex item is flushed with the cross-end edge of the line.
    center
    The flex item's margin box is centered within the line on the cross-axis. If the cross-size of the item is larger than the flex container, it will overflow equally in both directions.
    baseline
    All flex items are aligned such that their baselines align. The item with the largest distance between its cross-start margin edge and its baseline is flushed with the cross-start edge of the line.
    stretch
    Flex items are stretched such as the cross-size of the item's margin box is the same as the line while respecting width and height constraints.
