我把一个图片放到我的第一个asp.net core项目中，像一个背景，但当我把它，它也得到像一个页脚，我想在页眉和页脚之间。
我的共享_Layout代码。
@using CarRental.Common

我在首页的代码中，把背景放在了这里。
@using CarRental.Common
@{
this.ViewData["Title"] = "Home Page";
}
<style>
body {
background-image: url(/images/background-home.jpg);
background-repeat: no-repeat;
background-attachment: fixed;
}
</style>
<div class="text-center">
<h1 class="display-4" style="color:gold">Welcome to ElisCar! </h1>
</div>
我认为，我必须添加一些东西到首页index.cshtml，以解决我的问题，谢谢。
你需要给你的页脚一个背景色，就像你的页眉一样，例如
.footer {
background-color: #ffffff;
}
或添加bg-white类到你的 <footer> 标签。
<footer class="border-top footer text-muted bg-white">
你可以在页脚设置较高的z-index值。这样页脚就会显示在背景图片的上方。
