我对css网格有一个问题，我用css网格构建了一个包含两个div容器，我想把容器调整到页面中心。我使用以下代码：
null
html{
width: 100vw;
height : 100vh;
}
body{
height : 100%;
}
.container-fluid{
width:100%;
height : 100%;
display:grid;
grid-template-columns: 300px;
grid-template-rows: 200px auto;
justify-content: center;
align-content: center;
border:1px solid red;
}
.logo-container{
background-color: khaki;
}
.form-container{
height :540px;
background-color: lightblue;
}<!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">
<link rel="stylesheet" href="assets/css/style.css">
<link rel="stylesheet" href="assets/css/media-query.css">
<title>Login & Register User With Profile</title>
</head>
<body>
<div class="container-fluid">
<div class="logo-container">
<h1>Logo</h1>
</div>
<div class="form-container">
<h1>Form</h1>
</div>
</div>
<link rel="stylesheet" href="assets/css/all.css">
</body>
</html>null
如您所见，当网格容器高度大于页面高度时，就会出现问题（请参阅代码结果）。当使用高度为主体标签，网格高度溢出和当删除高度从主体标签，一切都是可以的，但在这个原位容器不能调整在页面中心的容器。什么是问题？
像下面这样简化代码：
null
body {
margin: 0; /* remove default margin */
}
.container-fluid {
min-height: 100vh; /* at least screen height */
display: grid;
grid-template-columns: 300px;
grid-template-rows: 200px auto;
justify-content: center;
align-content: center;
border: 1px solid red;
box-sizing:border-box; /* to consider the border inside the height */
}
.logo-container {
background-color: khaki;
}
.form-container {
height: 540px;
background-color: lightblue;
}<div class="container-fluid">
<div class="logo-container">
<h1>Logo</h1>
</div>
<div class="form-container">
<h1>Form</h1>
</div>
</div>
