无法在视频上对齐文本

Question

我设计了一个着陆页，但它在移动设备上无法正常工作。

Image 1 Mobile : This is what my interface looks like currently on mobile.

Image 2 Desktop : This is what it looks like on desktop.

问题：我希望移动设备的外观与桌面设备的外观相同。

我的代码如下：

body {
  position: relative;
  overflow: hidden;
  background-color:black;
  font-family: 'Chakra Petch', sans-serif;
  color: white;
}
 video {
  position: absolute;
  top: 0;
  width:100% !important;
  z-index: 1;/*  object-fit is not supported on IE  */
  object-fit: cover;
  opacity: 0.6;
}
 .container {
  z-index: 2;
  position: relative;
  padding-top: 200px;

}


.btn{
  background-color: #36454f !important;
  border-color: #36454f !important;
}

.btn:hover{
  background-color: #476376 !important;
}

Answer 1

您可以使用字体缩放和动态填充来完成这项工作

我做了什么：

将字体大小更改为 vw（视口宽度）
将内边距更改为 10%（从最初的 200 像素）
也使用 vw 为字幕添加了字体大小

如果您不喜欢这个结果，可以稍微调整一下值

这不是 100% 相同，但非常接近

注意：您还可以使用 calc（vw 和 px 一起）的混合方法来避免文本不可读，如下面的 link 中所述

body {
  position: relative;
  overflow: hidden;
  background-color:black;
  font-family: 'Chakra Petch', sans-serif;
  color: white;
}
 video {
  position: absolute;
  top: 0;
  width:100% !important;
  z-index: 1;/*  object-fit is not supported on IE  */
  object-fit: cover;
  opacity: 0.6;
}
 .container {
  z-index: 2;
  position: relative;
  padding-top: 10%;

}


.btn{
  background-color: #36454f !important;
  border-color: #36454f !important;
}

.btn:hover{
  background-color: #476376 !important;
}
