本页面按照字母顺序列出了Gecko所支持的所有CSS选择器, 属性, @规则, 媒体查询和值.
"开始支持" 一栏表示的是在Gecko哪个版本中引入了对该特性的支持,早于Gecko 1.0的版本也都列入了1.0中.
Gecko是Firefox和其他一些程序使用的渲染引擎,请查看Gecko页面来了解更多关于Firefox和Gecko版本号的知识.
"规范"一栏是个首次引入该特性的规范文档的链接.但很多情况下,这个特性既完全实现了上版规范,又部分实现了新版规范.
Mozilla CSS扩展(带有-moz-前缀)在"备注一栏中提供了bug号和其他相关提示.
警告: 很多的规范仍然处于工作草案状态,这些属性可能被修改,重命名,甚至被删除.
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.
