conflict with bootstrap sass

[NetanelBasal]

I have this imports in my scss file:

@import 'susy/susy';
@import 'juice/dist/juice';
@import 'breakpoint/breakpoint';
@import "bootstrap/bootstrap-sprockets";
@import "bootstrap/bootstrap";

and i get this error:

Error: Mixin size is missing argument $height.

for example:

div {
  @include coverer;
}

when i comment the last line its working fine.

Unfortunately the size mixin does have a conflict when Bootstrap is included as well since Bootstrap has a size mixin. I suppose I could add a Bootstrap variable to disable the overlapping mixins, something like $bootstrap: true.

I think you should cause bootstrap is essential in every project today.
