我的浏览器与我的CSS不匹配(但jQuery确实如此)

而这些jQuery调用:

var measures = $('.bio-target-measure');
measures.length; // evaluates to 1.
measures.is('.bio-target-measure:not(.lowerThird-25.lowerThird-active):not(.lowerThird-50.lowerThird-active):not(.lowerThird-100.lowerThird-active):not(.middleThird-25.middleThird-active):not(.middleThird-50.middleThird-active):not(.middleThird-100.middleThird-active):not(.upperThird-25.upperThird-active):not(.upperThird-50.upperThird-active):not(.upperThird-100.upperThird-active):not(.bud-25.bud-active):not(.bud-50.bud-active):not(.bud-100.bud-active)');
// evaluates to true.

var emptyMeasures = $('.bio-target-measure:not(.lowerThird-25.lowerThird-active):not(.lowerThird-50.lowerThird-active):not(.lowerThird-100.lowerThird-active):not(.middleThird-25.middleThird-active):not(.middleThird-50.middleThird-active):not(.middleThird-100.middleThird-active):not(.upperThird-25.upperThird-active):not(.upperThird-50.upperThird-active):not(.upperThird-100.upperThird-active):not(.bud-25.bud-active):not(.bud-50.bud-active):not(.bud-100.bud-active)');
emptyMeasures.length; // evaluates to 1.

但是满足选择器的这种元素的不透明度opacity: 0 !important;(正如使用jQuery看到的)是1.我的谷歌浏览器(47.0.2526.106,Ubuntu 15.04,64bits)浏览器仅使用第一条规则(唯一的是澄清:不透明度0的规则不存在但覆盖:匹配中完全不存在.

问题:是:不规则(我使用它)一个有效的CSS选择器？我知道它适用于jQuery,但我问的是CSS.
