CSS 关键帧不适用于 Firefox (23.0.1)

Question

我对@keyframes有问题。它与Chrome和Opera完美配合，但某些元素（big.h类或p）无法使用Firefox（最新版本23.0.1）进行动画处理。有趣的是，每个前缀都以相同的方式编写（-webkit-, -o- 或简单地@keyframes）图像正确动画。它是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_h和.da-slide p规则具有left属性的!important值。 CSS Animations规范草案曾经说动画覆盖了！important，但去年年底发生了变化。 见第一段末尾 http://www.w3.org/TR/2013/WD-css3-animations-20130219/#animations。 听起来Firefox已经更新以遵循规范，而Chrome和Opera还没有。
