无论如何，您应该自己尝试并提供您到目前为止所做的demo，并寻求帮助以解决问题。你应该放置你的 video 元素并将绝对位置宽度设置为 100% 宽度和高度。

video {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: auto;
}

.jumbotron {
    padding-top: 30px;
    padding-bottom: 30px;
    margin-bottom: 30px;
    color: inherit;
    background-color: #eee;
    height: 300px;
    overflow: hidden;
    position: relative;
}

.container {
    position: relative;
}
