A: Hey there, thanks for your question. The CSS files are all located in the following folder:

/wp-content/micro-themes/

And you can view them all from the Microthemer interface:

Settings > General > Generated code.

So you can go ahead and copy CSS code from there. However, there will be edge cases when the CSS doesn't quite work without Microthemer managing things. Like if you have used a Google Font via the special Google Font field (rather than the regular font-family field) - Microthemer will load the Google Font, but not if you just copy the CSS code to another site. There is a video which explains the preferable way to remove Microthemer but keep the CSS changes:

This isn't exactly your use case, but worth mentioning.

In summary, you can copy and paste the CSS elsewhere. But it's not guaranteed to work in exactly the same way 100% of the time.

I hope that helps. Please let me know if you have any further questions.

Thanks,
Sebastian
