Generic CSS alignment code that is shared between both the Flexbox and CSS Grid algorithms.

Functions

apply_alignment_fallback 🔒

Resolve any spec-defined fallbacks for the given AlignContent value, returning the bare position keyword the alignment math should use.

compute_alignment_offset 🔒

Generic alignment function that is used:

resolve_self_alignment_safety 🔒

Resolve the safe/unsafe overflow-position fallback for a self-level alignment value (used by align-self / justify-self-style sites and by absolutely-positioned items in flex/grid). If the alignment subject overflows its alignment container and the requested alignment is safe, fall back to logical Start per CSS Box Alignment https://www.w3.org/TR/css-align-3/#overflow-values. Otherwise drop the safety modifier and return the bare keyword.
