An attempt to import Global CSS from a file other than [`pages/_app.js`](https://nextjs.org/docs/advanced-features/custom-app) was made.
Global CSS cannot be used in files other than your [Custom `<App>`](https://nextjs.org/docs/advanced-features/custom-app) due to its side-effects and ordering problems.
#### Possible Ways to Fix It
Relocate all Global CSS imports to your [`pages/_app.js` file](https://nextjs.org/docs/advanced-features/custom-app).
Or, [update your component to use local CSS (Component-Level CSS) via CSS Modules](https://nextjs.org/docs/basic-features/built-in-css-support#adding-component-level-css). This is the preferred approach.
