If you compile less from .less into .css files, you can give it an option to minimize your css (which you should be doing anyway).
lessc -x styles.less > styles.css
Basically, run less with JS in development so you can see where things go strange. Then when happy, compile and minify for production. Multi-line for development is no big deal at all.
