Hey, this isn't CSS, its SASS (a preprocessor / better version of CSS), There're a lot of converters online from which you can convert SASS code to CSS Code, the one I use is Scout-App which is opensource and recommended by SASS developers. Source: almost 2 years ago

I don't know that extension (I'm using easy sass compiler) but you can try standalone app like https://scout-app.io/. Source: almost 2 years ago

You can use https://scout-app.io desktop app to process the styles if you are new to all this. Source: almost 3 years ago

Alternatively, you could run https://corz.org/windows/software/checksum/ on your music collection, and use the hash file to check that your backups are the same as the source. Source: about 1 year ago

The next thing you want to look into is file integrity. Files can get corrupted & if you update your backup with a corrupted version of the file the backup isn't much help. If you're hoping to retain data for an extended period of time look into file hashing. I use https://corz.org/windows/software/checksum/ but there likely better options out there, I haven't looked recently. I like that the corz checksum... Source: over 2 years ago
