/* FIXME: the media query is only necessary due to the fact that Module:Gallery uses inline styles.
Module:Gallery should be updated to not use style attributes and exclusively use this.
Various other templates use Module:Gallery, so out of fear of breaking them I've done this (mixed with importants) which make me very sad.
