php - HTML5 视频背景无法加载

Question

Newb 在这里再次尝试超出他们技能范围的事情，以扩展技能范围。

我正在尝试让一个循环播放的视频作为我的小表格的背景(新手尝试一些新的东西作为学习练习)。一切似乎都已加载，链接/路径正确，文件已上传到它们的文件夹等。我已经查找拼写错误并检查了我的括号、冒号和分号等。我已经尽我所能，但我我还没有完全“到位”，因为视频没有按预期播放。

你的 source 标签上的 type 属性不正确，它们应该是

<source src="_bgVideo/bg_vidLoop.mp4" type="video/mp4"/>
<source src="_bgVideo/bg_vidLoop.ogv" type="video/ogg"/>
