Bootstrap Studio：在页面中央放置一个超大屏幕

Question

这就是我想要的

这就是我得到的... 我尝试添加 rows/columns 但它们只会影响从上到下的移动，我以前可以在超大屏幕的左侧放置一个 column/row 但现在我不能了......是列和行有什么我遗漏的吗？

这是我的代码：

<html>

<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Mailsafe</title>
    <link rel="stylesheet" href="bootstrap.min.css" />
    <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Bitter:400,700" />
    <link rel="stylesheet" href="Header-Dark.css" />
    <link rel="stylesheet" href="styles.css" />
</head>

<body id="hero" style="background-color:#004878;">
    <section class="d-flex mse spacer" id="hero">
        <div id="hero-top"></div>
        <div id="hero-bottom"></div>
    </section>
    <div>
        <div class="container">
            <div class="row">
                <div class="col">
                    <div class="jumbotron flex-grow-0 flex-shrink-1" id="gateway">
                        <h1 class="text-center">Company Name</h1>
                        <p class="text-center"><br />Company blah blah<br />company blah blah blah.<br /><br /></p>
                        <p class="text-center"><a class="btn btn-primary" href="#" style="  width:673px;
">Get Started →</a></p>
                    </div>
                </div>
            </div>
        </div>
    </div>
</body>

</html>

Answer 1

在主体上添加 100% 高度，在容器包装上添加 html 和 d-flex h-100 align-items-center类 div。此外，从“入门”锚点中删除宽度并向其添加显示块。

html,
body {
  height: 100%;
  margin: 0;
}
