[css-align] justify-items: legacy fails to fulfil its only purpose of explaining <center> and align (original) (raw)

This keyword causes the value to effectively inherit into descendants.

If the legacy keyword appears on its own (without an accompanying left, right, or center keyword): if the inherited value of justify-items includes the legacy keyword, this value computes to the inherited value; otherwise it computes to normal.

When justify-self:auto references the value of justify-items, only the alignment keyword, not the legacy keyword, is referenced by it. It exists to implement the legacy alignment behavior of HTML’s <center> element and align attribute.
