firefox - CSS 关键帧不适用于 Firefox (23.0.1)

Question

@keyframes 有问题。它适用于 Chrome 和 Opera，但某些元素（big.h 类或 p）无法在 Firefox（最新版本 23.0.1）中生成动画。有趣的是，每个前缀都以相同的方式编写（-webkit-、-o- 或简单的@keyframes）图像动画正确。它是经过修改的视差内容滑块。我将非常感谢您的帮助。

问题是.da-slide .big_hand.da-slide p规则具有属性!important的值left。CSS Animations 规范草案曾经说过动画会覆盖 !important，但去年年底发生了变化。请参阅http://www.w3.org/TR/2013/WD-css3-animations-20130219/#animations第一段结尾。听起来 Firefox 已经更新以遵循规范，而 Chrome 和 Opera 还没有。
