【问题描述】：

我正在尝试在头像后面添加一个file input 字段。单击头像时，用户应该能够选择图像。它工作得很好，但是我如何隐藏输入字段（请参阅 sn-p）。当我添加visible: hidden 时，它会消失，但显然它不再是可点击的了。

我该如何解决这个问题？我正在使用TailwindCss:

<link href="https://unpkg.com/tailwindcss@^1.0/dist/tailwind.min.css" rel="stylesheet"/>


<div class="flex items-center cursor-pointer justify-center relative w-16 h-16 rounded-full border-2 border-brand-100">

谢谢！

【参考方案2】：

你可以那样做，这不是官方的做法，但在这种情况下你可以使用这种方法

input[type='file'] 
  opacity: 0;
