Not exactly
it's a mobile first project, so i use a _base.scss file, where my target is declared, but not declared in any media queries rules. On top of that, i've got two other scss (768 & 1024), where the target might be declared.
But, with grunt, those 3 files are compiled in one single styles.css file.
But even by removing the loading part of the media queries, it does not change anything :/
