如何使此容器和表格响应移动设备和 ipad 大小？

Question

我想尝试将其变成桌面平板电脑和手机的响应式设计，我很难让 youtube 视频响应式 - 有人可以帮忙吗？谢谢 真的很感激

我在想我需要对 CSS 进行某种媒体查询，但我不确定该怎么做 - 真的很感激，因为有人可以向我解释它是如何工作的

Answer 1

1) 我已经为 JSFiddle 准备了工作示例。该视频现在是响应式的，但我不知道您希望如何准确定位视频和表格。 http://jsfiddle.net/8w2m9xdz/1/

2) 我已经更新了你的代码。视频是响应式的。当你缩小窗口时，表格在视频下方，所以它在移动设备上应该很好，但你需要自己测试它。

  margin-bottom: 20px;

.mytable td {
  color: #22313F;
  text-align: left;
  border-radius: 0.75em;

.mytable tr {
  -webkit-transition: background 0.3s, box-shadow 0.3s;
