Revision Content

This document is in the process of being migrated from {{template.Bug(281960)}}. It will be hooked into the category system when it's complete.

Introduction

This page lists the CSS selectors, properties, and at-rules for which Mozilla has implemented some level of support. Such lists are a very coarse measure of CSS support. Implemented features may have (filed or unfiled) bugs, and therefore may not work correctly under all conditions.

If you think you have found a bug in Mozilla's CSS support please create a minimal test case and file a bug. Make sure you search through existing bugs first.

The ‘supported since’ column gives the Gecko version number. (Firefox 1.0 is built from Gecko 1.7.5. Mozilla Suite version numbers are equal to those of Gecko.) Versions prior to version 1.0 are listed as 1.0.

Mozilla CSS extensions (those prefixed with -moz-) are not listed here. They are intended for internal use within the browser only and must not be relied upon to work in web pages, because they can and will break.

This page lists several Mozilla bugs so people can check out what the problems are with our implementation. Please do not comment on any of those bugs unless you have a patch.
