我需要帮助这个脚本转换视频css3和js编写的克里斯蒂安海尔曼。 它可以在safari和chrome上运行,但不能在firefox上运行……任何人都可以告诉我为什么

这是小提琴:

js代码如下所示:

对于(i=0,j=properties.length;i示例页面上的旋转效果很好。视频不会播放,因为您仅以Firefox不支持的格式提供(至少在我的平台上)。请在中提供另一种格式

您的浏览器似乎不支持HTML5视频标签。

Ok。Safari和chrome使用webkit引擎呈现和显示HTML,而firefox使用Gecko。这会造成差异。使用webkit支持的CSS3属性,不幸的是,firefox不支持这些属性,因为您的小提琴不包含视频。请在视频中添加或,并更新fiddle@AkshaYKANTHELWAL——教程URL在Firefox中运行良好(Christian Heilmann为Mozilla基金会工作)!EHI家伙!小提琴被更新了,昆廷的代码和OGV文件链接在JSFIDDL.NET上,但是在我的页面上没有,大家知道为什么吗?
