我想要的视频元素只有屏幕宽度的70%,但我仍然需要保持高度宽高比100%。现在我有全宽视频作为背景。
我正在使用bootstrap v4。
<body>
<video poster="assets/img/gpd.jpg" id="bgvid" playsinline autoplay muted loop>
<source src="assets/video/gpd_video.webm" type="video/webm">
</video>
<div class="site-wrapper">
<div class="site-wrapper-inner">
<div class="cover-container">
<div class="masthead clearfix">
<div class="inner">
<h3 class="masthead-brand">Cover</h3>
<nav class="nav nav-masthead">
<a class="nav-link active" href="#">Home</a>
<a class="nav-link" href="#">Features</a>
<a class="nav-link" href="#">Contact</a>
</nav>
</div>
</div>
<div class="mastfoot">
<div class="inner">
<p></p>
</div>
</div>

</div>
</div>
</body>
CSS:
video {
position: fixed;
top: 50%;
left: 50%;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
transform: translateX(-50%) translateY(-50%);
background-size: cover;
transition: 1s opacity;
}
我希望有这样的结果:
有可能吗?
答案 0 :(得分:1)
video {
position: fixed;
top: 50%;
left: 50%;
min-width:70%;
min-height: 100%;
width: auto;
height: auto;
transform: translateX(-50%) translateY(-50%);
background-size: cover;
transition: 1s opacity;
}
//我建议你使用这个css,通过设置min-width:70%你的视频只占你视口的70%:)
