更改html5视频元素的背景颜色
问题描述：
我有以下网站：
beta.leifsigersen.com
I've got the following website: beta.leifsigersen.com
前端有一部电影，有时需要一段时间才能载入（有时少于一秒，有时几秒）。在电影加载之前，有黑色背景/边框。如何更改此颜色？
There's a movie on the front page which sometimes takes a little while to load (sometimes less than a second, sometimes a few seconds). Before the movie is loaded there's black background/borders. How can I change the color of this?
我试图使用视频元素的CSS，但没有运气。
I've tried to use CSS of the video-element, but without any luck.
答
试用此CSS：
.pk_video {
background-color: red !important; /* or whatever you want */
}
