3-valued CSS position is no longer supported except for background-position

Published: | Categories: CSS

Description

Firefox 70 has dropped the support for the 3-valued position syntax for the object-position, perspective-origin and mask-position properties as well as the circle and ellipse shape functions, according to the current CSS Values spec. Only the 1, 2 or 4-valued syntax can be used from now on, though the background-position property still accepts the 3-valued syntax like left 10px top.

Google Chrome has made the same change in version 68.
