我已经将视频的现有代码嵌入为iframe。我想将此视频转换为16:9的宽高比。我无法更改应用于类.parent1
的CSS。有什么帮助通过CSS实现吗?
.parent1 {
position: absolute;
left: 37%;
top: 14%;
}
<div class="parent1">
<div class="parent2">
<iframe width="560" height="280" src="https://www.youtube-nocookie.com/embed/-UD4yHnEMeM" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>
</div>

这是引导响应式嵌入的简单方法:

主要是:
.parent {
position: relative;
display: block;
width: 500px; // you will most like use 100% to fit into its parent
padding: 0;
}
.parent::before {
content: '';
display:block;
padding: 56.25% 0 0 0;
}
.parent iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
这里在引导程序自己的网站上起作用:https://getbootstrap.com/docs/4.1/utilities/embed/
