FYI: Preferences to disable prefixed properties have been added

Published: | Categories: CSS


While this is not a change affecting site compatibility, it’s worth mentioning because this has been developed as part of efforts to keep compatibility. Preferences to disable some major prefixed properties have been added: layout.css.prefixes.border-image, layout.css.prefixes.transforms, layout.css.prefixes.transitions and layout.css.prefixes.animations. Web developers can disable those preferences (change the values to false) to test whether style rules are applied as intended even after those prefixed implementations are removed. See the David Baron’s blog post for details.
