Could you explain why this is better?
Currently I read that there is a css variable in line 313
This is also used in line 322/320

Now that the else statement is not there anymore, the css variable gets minified also if line 313 gets executed.
Was this intended?

Good catch @Shinigami92, corrected the code to avoid minification when not inlined

[Shinigami92]

Yeah, now it makes sense 👍

I had read somewhere that minifying allow for faster parsing so if this is true then if this css file will be parsed for e.g if a css class will be used then the analysis could be faster if minified.
However I don't know the topic nor do I even know if the unused check has granularity over css classes/selectors or is per file.
So my comment probably is irrelevant and wrong but I'm still saying it in case someone more knowledgeable thinks this is relevant
