好的，所以我的网站在实际内容的背景中有一个视频，可以在我的网站上看到示例：
http://www.thespire.net/
当视频仍在播放时，如何在视频上放置图像？我尝试将其合并到JavaScript和某些标签中，但它总是弄乱我网页的格式。

最佳答案
我可以看到您有一个名为info的div：
<div class="info"> </div>
如果您添加此CSS：
.info {
background: rgba(0, 0, 0, 0) url("http://www.thespire.net/spirelogo.png") no-repeat scroll 0 0;
}
如果要完全覆盖滑块，则需要更多自定义。
