html - 尽管代码正常，但登录页面无法正常工作

Question

最近，我得到了一个使用 HTML 和 CSS 创建的登录页面。它包含在 css 代码中的样式未显示在结果中。我已经浏览了整个代码几次，但对我来说似乎一切都很好。它没有给出根据 css 代码应有的结果。请告诉我真正的问题是什么？是否是代码？或别的东西:) 代码：

必须比较标签。您必须添加另一个，因为在第 1 行您开始了一个新的 div 而没有结束它。

固定代码：

body {
    background: #222D32;
    font-family: 'Roboto', sans-serif;
}

.login-box {
    margin-top: 75px;
    height: auto;
    background: #1A2226;
    text-align: center;
    box-shadow: 0 3px 6px rgba(0, 0, 0, 0.16), 0 3px 6px rgba(0, 0, 0, 0.23);
}

.login-key {
