This shows an issue which occurs in Astro.js, but only in production builds.
There are two layouts being used here, both are the same, and both import a MainHead component, which in turn imports global css.
There are three pages in this example:
- index: Uses Main layout
- beta: Uses Second layout
- admin: Does not use Main layout, imports
MainHeaditself.
The global css turns buttons green, but the main layout imports a file that wraps a Button component and applies a class to turn it blue.
When building in dev, the button is blue.
Run npm run build then npm run preview, and the button will be green.
Deleting any one of the pages seems to avoid this issue.
Removing the postcss.config.cjs also fixes the issue.
NOTE: When making changes, you may need to rename the project's root folder before rebuilding, in order to clear some kind of internal Astro cache. It doesn't hurt to launch the site with a fresh port, too, like npx http-server dist -p 8009.
