I simply have the code
@def WIDTH 50 // will be reused
width: @def WIDTH px // incorrect space between
I believe CSS doesn't allow the space between # and px which makes this code wrong. But I haven't found a string concat function. Is there a way to do this?
I'm aware I can @def WIDTH to be 50px, that will break its reuse.
A correct Closure solution to this problem is to
mult by the unit.
width: mult(1px, WIDTH);
