Tips for implementing custom styles on React components that have been imported locally

I'm currently struggling with applying CSS successfully to components imported from an npm library. My main challenge seems to be my use of css-loader in the react starter kit (https://github.com/kriasoft/react-starter-kit) without a full understanding of its functionality.

While exploring various datepicker libraries like https://github.com/YouCanBookMe/react-datetime and https://github.com/wangzuo/input-moment, I noticed that these libraries assign local class names to HTML elements, making it challenging to automatically apply embedded formats. I've tried importing styles from /node_modules manually into the component using the library component. Alternatively, I attempted copying relevant styles to a local CSS file and importing them, but neither approach seemed to work smoothly.

The issue appears to stem from css-loader converting imported styles' class names into module-specific class names that do not align with the actual class names found in the resulting HTML code.

Am I going about this the wrong way? What is the recommended method for importing components and implementing custom styling effectively?

Thank you!

Answer №1

After some trial and error, I discovered that simply wrapping the classnames in :global() within the css file solved the issue for me. Here's an example:

:global(.myclass) {
   color: red;
}

This method preserved the original class names without any modifications and allowed them to apply correctly to the HTML elements. While I'm not sure if this is considered best practice, it did resolve my problem.
