Hello everyone, I recently encountered a problem. I'm trying to set a video background to my site, but the centered text runs all the way to the bottom, I don't know why, yet the navigation bar is fine. I've done a lot of research but can't find a solution.
For CSS, I made the following settings:
*{
margin: 0;
padding: 0;
box-sizing: border-box;
font-family: TESLA Regular;
}
.hero{
width: 100%;
height: 100vh;
background-image: linear-gradient(rgba(12,3,51,0.3));
position: relative;
padding: 0 5%;
display: flex;
align-items: center;
justify-content: center;
}
nav{
width: 100%;
position: absolute;
top: 0;
left: 0;
padding: 20px 8%;
display: flex;
align-items: center;
justify-content: space-between;
}
nav .logo{
width: 150px;
}
nav ul li{
list-style: none;
display: inline-block;
margin-left: 40px;
}
nav ul li a{
text-decoration: none;
color: #fff;
}
.content{
text-align: center;
}
.content h1{
font-size: 160px;
color: rgb(110, 57, 57);
font-weight: 600;
transition: 0.5s;
}
.content h1{
-webkit-text-stroke:2px rgb(212, 28, 28) ;
color: transparent;
}
.back-video{
position: absolute;
right: 0;
bottom: 0;
z-index: -1;
}
@media (min-aspect-ratio: 16/9){
.back-video{
width: 100%;
height: auto;
}
}
@media (max-aspect-ratio: 16/9) {
.back-video {
width: auto;
height: 100%;
}
}
> 对于HTML，我做了以下设置
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="hero">
<video autoplay loop muted plays-inline>
<source src="mylive.mp4" type="video/mp4">
</video>
<nav>
<img src="2086940.jpg" class="logo" alt="">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">Zone</a></li>
<li><a href="#">Gaming</a></li>
<li><a href="#">Blog</a></li>
<li><a href="#">About us</a></li>
</ul>
</nav>
<div class="content">
<h1>Gaming is not a crime!</h1>
</div>
</body>
</html>

Yes, it is possible to add a video as a background using HTML and CSS.
1) Add the video tag and video reference in the HTML file as follows:
<video autoplay muted loop id="myVideo"> <source src="rain.mp4" type="video/mp4"> </video>
2) Set the width and height to 100% to cover the entire window and use position fixed to set the video as background. You may encounter visibility-related issues, but these can be solved using z-index and background overlay effects.
#myVideo {
position: fixed;
right: 0;
bottom: 0;
min-width: 100%;
min-height: 100%;
}
