Example of using basscss rails helpers for components. Note: this is from memory and not tested, so it may not be perfect, or even syntactically correct for that matter : )

basscss_card_helper.rb

module BasscssCardHelper
  def bass_card(tag = :div, opts = {}, &block)
    content = capture(&block)
    opts[:class] = bass_card_classes(opts[:class])
    content_tag(tag, content, opts)
  end
  
  def bass_card_for(tag, record, options, &block)
    content = capture(&block)
    opts[:class] = bass_card_classes(opts[:class])
    content_tag_for(tag, record, options, content)
  end

  def bass_card_classes(additional_classes = '')
    card_classes = 'bg-navy border rounded mt2 p2'

    if additional_classes.present?
      "#{ card_classes } #{ additional_classes }"
    else
      card_classes
    end
  end
end
