使用Tailwind CSS无法实现表单居中，请求技术协助

你的Login文本已成功居中，但表单停留在页面左侧，核心问题出在包裹表单的div上：虽然你添加了flex flex-col justify-center items-center，但这个容器本身没有占据足够的空间，导致这些flex布局属性无法发挥预期作用。

修复方案 #

给包裹表单的div添加min-h-screen（让容器占满整个视口高度，实现垂直方向居中）和mx-auto（确保容器在水平方向上居中），修改后的容器类如下：

<div class="w-full max-w-xs min-h-screen flex flex-col justify-center items-center mx-auto">

如果不需要表单垂直居中，仅需水平居中，也可以简化为：

<div class="w-full max-w-xs mx-auto">

修改后的完整代码 #

<div class="text-center text-black text-lg font-mono decoration-2">
    <h1>
        Login
    </h1>
</div>
<div class="w-full max-w-xs min-h-screen flex flex-col justify-center items-center mx-auto">

<form method="POST" action="{{ route('login') }}" class="bg-white shadow-md rounded px-8 pt-6 pb-8 mb-4 ">
