想請問下使用create-react-app腳手架創建項目后 是否css文件只有放在src根目錄下才能引用？我在src目錄下創建了一個名為css文件夾然 后引入css文件就報錯了Module not found: You attempted to import /src/css/my.css which falls outside of the project src/ directory. Relative imports outside of src/ are not supported. You can either move it inside src/, or adda symlink to it from project's node_modules/.后來我發現引入的css文件和js文件只需要在一個文件夾里就可以使用了請問怎么才能實現在src/css文件下引入css文件？謝謝
