What was the replacement for "container" in Susy 3?

Question

Sass

In the second version @include container(90%), I used to set a container on the page with a width of 90%. Now I installed Susy 3 and in Gulp I catch the error "Error: no mixin name container". How to decide?

Answer 1

There are no more mixins, only functions - https://twitter.com/SassSusy/status/894295590019809280

Answer 2

With container, everything is simple. You just need to create a mixin:

=container($value)
  max-width: $value
  margin-left: auto
  margin-right: auto
