我需要在模态对话框modal-sm类中显示视频标签，以便视频以整个模态显示，我设置在视频标签宽度：640和高度480，但它只显示在模态体类中我不喜欢＃39;知道如何将整个视频对象扩展为整个div对象。

试试这个：
将此内容添加到您的CSS文件中：
.videoAdd {
position: absolute;
right: 0;
bottom: 0;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -100;
background-size: cover;
overflow: hidden;
}
并在HTML文件中尝试添加此Div并在其中添加视频标记：
<div class="wrapper">
<video class="videoAdd">
<source src="yourVideoSrc" type="video/mp4">
<source src="anotherVideoSrc" type="video/ogg">
</video>
</div>
