使HTML视频背景全高

时间：2016-08-02 01:35:42

标签： css html5

基于Pen in codepen.io我试图通过HTML5和CSS3实现全屏视频背景。

这里的问题是，如果视口是移动设备（9:16）之一，它会留下一个＆＃34;空白＆＃34;视频下的空间。

尝试添加＆＃34; 100vh＆＃34;对于视频课程，然后文本的容器不会居中，容器之间会有很大差异。

HTML（刀片）：

我不认为JS在这里是相关的，但如果需要，我会添加它。

2 个答案:

答案 0 :(得分：0)

全尺寸视频

在header中，您有：

header {
    min-height: auto;
}

您应该将其更改为：

header {
    min-height: 100%;
}

居中文字

在您的landing.css中，媒体查询超过768像素的内容。你想要：

  1. 从媒体查询中剪切header .header-content的CSS。

  2. 将其粘贴到不在媒体查询中的header .header-content上。

答案 1 :(得分：0)

不确定你是否会100％满意，但我尝试过（并且对此感到满意）是：

header, .header-content {
  height: 100%;
}
.inner {
  position: relative;
  top: 50%;
  margin: -5em auto 0;
}

它使视频在屏幕中间100％高度+标题文本
