我在 body 背景图像中添加了黑色透明渐变，但是当我将 Bootstrap 添加到 html 文件时，它停止工作。
body {
background:
linear-gradient(
rgba(0, 0, 0, 0.5),
rgba(0, 0, 0, 0.5)
),
url("https://picsum.photos/id/1000/800/800");
background-size: cover;
}<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">最佳答案
按照此链接中给出的示例 -> https://mdbootstrap.com/docs/jquery/css/background-image/
HTML
<body>
<div class="bg"></div>
<p class="py-5 text-center">This example creates a full page background image. Try to resize the browser window to see how it always will cover the full screen (when scrolled to top), and that it scales nicely on all screen sizes.</p>
CSS
body, html {
height: 100%;
}
.bg {
/* The image used */
background-image: url("https://mdbootstrap.com/img/Photos/Horizontal/Nature/full page/img(20).jpg");
/* Full height */
height: 100%;
/* Center and scale the image nicely */
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
关于html - 有色背景图像不适用于 Bootstrap，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57532500/
