我想在我的 Laravel 8 应用中应用 tailwind-starter-kit 我从 html-login-page/login.html 文件中获取了编辑器表单，并且此表单的“登录”页面包含类：

<button class="bg-gray-900 text-white active:bg-gray-700 text-sm 
    font-bold uppercase px-6 py-3 rounded shadow hover:shadow-lg 
    outline-none focus:outline-none mr-1 mb-1 w-full"
        type="button" style="transition: all 0.15s ease 0s;">
    Sign In
</button>

我想在 resources/css/app.css 中设置类定义，如下所示。

.btn_full {
    @apply bg-gray-900 text-white active:bg-gray-700 text-sm 
    font-bold uppercase px-6 py-3 rounded shadow hover:shadow-lg 
    outline-none focus:outline-none mr-1 mb-1 w-full;
}

但是我收到以下错误。

(623:39) /project_path/resources/css/app.css The active:bg-gray-700 class does not exist, but hover:bg-gray-700 does. If you're sure that active:bg-gray-700 exists, make sure that any @import statements are being properly processed before Tailwind CSS sees your CSS, as @apply can only be used for classes in the same CSS tree.
