Render部署后Tailwind CSS样式不生效问题求助

我在Render上部署了个人作品集，本地运行时Tailwind CSS样式显示正常，但部署后样式完全加载不出来。作为Tailwind新手，我怀疑问题出在Webpack对Tailwind类的路径引入配置上。

以下是我的配置文件：

tailwind.config.js #

/** @type {import('tailwindcss').Config} */
module.exports = {
  important: true,
  content: ["./src/**/*.{html,js}"],
  theme: {
    extend: {},
  },
  plugins: [],
}

package.json #

我已经尝试过以下操作，但都没能解决问题，甚至多次导致构建失败：

• 修改Webpack配置以支持CSS
• 在src目录添加style.css文件
• 调整构建命令

恳请大家帮忙排查问题。
