How to off-set Columns in Susy Grid System?

Question

I want to Off-Set Columns using Susy, like off-setting columns in Bootstrap.

I tried to use

@include span(4 at 4);

But that doesn't work. What I'm doing wrong?

Answer 1

I just found out how to do this.

There is two functions (or mixins) called "push" and "pull"

@include push(4);
@include pull(4);

And that's really it :)
