module Flowbite
  # Renders a card element.
  #
  # To render a title in the card, use the title argument or the title slot.
  #
  # @example Using the title slot
  #     <%= render(Flowbite::Card.new) do |card| %>
  #       <% card.with_title do %>
  #         <div><%= parent_category.name %></div>
  #         <%= render(Flowbite::Card::Title.new) { category.name } %>
  #       <% end %>
  #     <% end %>
  #
  # @viewcomponent_slot [Flowbite::Card::Title] title The title of the card,
  #   rendered at the top. Use +with_title+ to set custom content.
