The alignment properties align-self and justify-self are defined to work in absolute positioning in Level 3: https://www.w3.org/TR/css-position-3/#abspos-layout However, this is not implemented yet in WebKit. See additional details in css-align-3: https://www.w3.org/TR/css-align-3/#justify-abspos https://www.w3.org/TR/css-align-3/#align-abspos and integration with anchor positioning in css-anchor-position-1: https://www.w3.org/TR/css-anchor-position-1/#positioning
