I haven't managed to find any information about the CSS @import handling methods of minification available in the options. I'm trying to understand which does what... If you don't know the answer to this question already, don't waste too much time looking for answers to my questions - I'm going to find out by experimenting anyway, eventually, and then I'll return with answers to my own questions...
I'm customizing a theme by creating a child theme which imports the style.css of the parent theme, which of course is in a different folder, and I'm wondering what the differences between Process and Bubble @import handling would be in this case / in general.
Specifically, regarding minification, would there be a problem (with any of the two @import handling methods) if the parent theme's style.css used @import as well? I'm worried that deeply imported CSS may not be minified in one case, or may not even be included at all (inner-more @imports ignored altogether).
Other things that concern me are whether any of the @import handling methods prevents the respective CSS files from getting combined and whether relative paths used in those CSS files still work in all cases.
