Helper Class

Helper class is a set of tools to allow site builder to easily set CSS helper classes on Drupal Elements.
For now it handle :

• Entity
• Views rows and wrapper

It could help to easily create card grid (for bootstrap for exemple).
And could be completed with Fieldgroup and Field Formatter Class

This is a lightweight alternative to handle assembly of organism and template of a website based on component library.

Handle organism and template with just helper class.
And handle atoms and molecule with SDC.
Like this you could keep the flexibilty for site builder to reuse component without depending on complex user interface but just helper classes.
