如何解决html5视频不会在野生动物园中显示，但可以在Chrome上显示
我的页面上有一个视频滑块。这是网站http://shekleung.com/projects.html 该代码可以在chrome和ios Safari上完美运行，但不能在桌面上运行。在通过Safari浏览网站时，该视频会显示在html页面中，甚至会高亮显示应该位于的位置。我知道滑块是有效的，因为文本元素根据所显示的影片而变化。我对野生动物园中根本不显示的情况感到困惑。我只能怀疑大小不对吗？我正在使用香草js和CSS创建滑块。它显示良好，即使在iPhone上，滑块也可以正常工作。

解决方法
您可以尝试重命名视频，使其名称中没有所有空格吗？我在浏览器调试模式下尝试了它，似乎可以正常工作！
,好的，因为-
- apple要求在html 5视频元素上使用“ playinline”属性
- 重要-我们必须提供背景图片（“海报”属性），以供用户不播放视频时使用。 Chrome会自动执行此操作-生成框架，但Safari在视频标签中要求使用该框架，或者它显示为空白。
