How to modify paths inside CSS url().

[BUPTlhuanyu]

I created a plugin that uses resolveId to modify image file paths in JavaScript imports, for example changing ./assets/demo.png to ./assets/demo.png?no-inline. However, the resolveId hook cannot process background-image:url('./assets/demo1.png') in CSS/LESS/SASS files.

If using a PostCSS plugin, it needs to be added in the css.postcss configuration, but this causes Vite to stop looking for the local postcss.config.js file. So, can Vite expose a configuration option to modify url() in CSS?
