defmodule ComfycampWeb.CoreComponents do @moduledoc """ Provides core UI components. At first glance, this module may seem daunting, but its goal is to provide core building blocks for your application, such as modals, tables, and forms. The components consist mostly of markup and are well-documented with doc strings and declarative assigns. You may customize and style them in any way you want, based on your application growth and needs. The default components use Tailwind CSS, a utility-first CSS framework. See the [Tailwind CSS documentation](https://tailwindcss.com) to learn how to customize them or feel free to swap in another framework altogether. Icons are provided by [heroicons](https://heroicons.com). See `icon/1` for usage.
