我正在使用bootstrap,我想在背景上设置youtube视频
我找到了这个.如何更改此代码以使用来自youtube的视频？替换不起作用
@import url('http://fonts.googleapis.com/css?family=Oswald');
body {
margin: 0;
padding: 0;
background-attachment: fixed;
background-size: cover;
}
#video-background {
position: fixed;
right: 0;
bottom: 0;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -100;
} <video autoplay="" loop="" class="fillWidth fadeIn animated" poster="https://s3-us-west-2.amazonaws.com/coverr/poster/Traffic-blurred2.jpg" id="video-background">
<source src="https://s3-us-west-2.amazonaws.com/coverr/mp4/Traffic-blurred2.mp4" type="video/mp4">
</video>当我们将鼠标悬停在链接上时，我试图使导航栏完全突出显示，但它目前只能水平工作。我认为这是我做错的很小的事情并且已经尝试了四个小时。这是我的代码：
html, body {
/*require html and body 100% height and width to allow other child elements to use percentages*/
height: 100%;
width: 100%;
margin: 0;
}
a {
text-decoration: none;
display: block;
color: black;
}
li {
list-style: none;
}
div{
margin-left: 2.5%;
margin-right: 2.5%;
margin-top: 1%;
border: 1px solid black;
}
.content_section{
height: 150%;
margin-bottom: 1%;
}
#footer{
height: 25%;
margin-bottom: 1%;
}
#banner{
margin-top: 2.5%;
height: 15%;
position: relative;
}
#banner img{
width: 100%;
height: 100%;
} …
