Error when gutter-position set to “split” and gutter to “0”

[brandondurham]

My settings:

$susy: (
    math: fluid,
    gutter-position: split,
    container: 1100px,
    columns: 12,
    gutters: 0,
    global-box-sizing: border-box
);

I was getting this error:

message: 'invalid null operation: ""16.66667%" plus null".'

… when using a margin mixin:

@include push(2 of 12);

The fix was to change gutter-position to “after”:

$susy: (
    math: fluid,
    gutter-position: after,
    container: 1100px,
    columns: 12,
    gutters: 0,
    global-box-sizing: border-box
);
