如何使视频的宽度为100%或高度为100% [英] How to make video's width 100% or height 100%

您几乎了解了这一点,却错过了视频代码的大小.对象位置也可能很方便:
.remoteVideo {高度:100%;/*或max-height:100%;*/宽度:100%;/*或max-width:100%;*/适合对象:包含;object-position:center;转换:scale(-1,1);}
可能会在整个页面中运行示例,以测试调整大小或基于 max-height
/ max-width
100%
的版本时的行为 https://codepen.io/gc-nomade/pen/bGNzzNj 缩小视频如果它变得比屏幕大.您可以选择高度和宽度的值.
body {边距:0;}.remoteVideo-container {位置:固定;左:0;最高:0;z索引:0;宽度:100vw;高度:100vh;文本对齐:居中;background-color:rgb(45,48,53);}.remoteVideo {高度:100%;宽度:100%;适合对象:包含;对象位置:中心;转换:scale(-1,1);}

I'm having the same issue as this, but i'm trying to do it on <video/>
element.
I want to make video element sometimes width: 100%
, and sometimes height: 100%
by aspect ratio of it.
Here's my css
.remoteVideo-container {
position: fixed;
left: 0;
top: 0;
z-index: 0;
width: 100vw;
height: 100vh;
text-align: center;
background-color: rgb(45, 48, 53);
}
.remoteVideo {
object-fit: contain;
transform: scale(-1, 1);
}
here's my jsx
<div className="remoteVideo-container">
<video
className="remoteVideo"
autoPlay
ref={this.remoteVideo}
muted
></video>
</div>
Result:
You almost got it, you missed the sizing of the video tag. object-position could be also handy :
.remoteVideo {
height:100%; /* or is max-height:100%; */
width:100%; /* or is max-width:100%; */
object-fit: contain;
object-position:center;
transform: scale(-1, 1);
}
Possible example to run in full page to test behavior on resize, or version based on max-height
/max-width
100%

body {
margin: 0;
}
.remoteVideo-container {
position: fixed;
left: 0;
top: 0;
z-index: 0;
width: 100vw;
height: 100vh;
text-align: center;
background-color: rgb(45, 48, 53);
}
.remoteVideo {
height: 100%;
width: 100%;
object-fit: contain;
object-position: center;
transform: scale(-1, 1);
}
<div class="remoteVideo-container">
<video class="remoteVideo" autoplay muted poster="https://s3-us-west-2.amazonaws.com/s.cdpn.io/4273/polina.jpg">
