Document Inheritence of Layout Settings

Yes, this is supported natively by the Symfony YAML parser

You can define a reference using the & symbol, e.g. this at the top of your file defines a 'spacing' variant.

spacing: &spacing
  label: 'Spacing'
  require: true
  default: 'section'
  options:
    'section--no-padding': 'None'
    'section--half-padding': 'Small'
    'section': 'Large'

Then you can use that in your definitions like so:

one_column:
  label: One column
  category: Layouts
  template: layouts/one-column
  classes:
    spacing:
      <<: *spacing

Wow, thats awesome, thank you so much!

Thanks @larowlan - I never saw that before, very nice!

I guess others also might not be aware of this method. @thomas.frobieter perhaps it would make sense to prepare a MR with a README.md entry with this example for the module?

Or should it be added to the module description (page) @larowlan?

Even if this isn't something the module provides itselt, I think it would be useful to have an example and a link to the docs here?

Should we use this thread as a starting point for some module docs in general? Feedback please :)

And thank you very much for this hidden achievement again ;)
