defmodule MedicalTranscriptionWeb.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.

Renders a [Heroicon](https://heroicons.com).
Heroicons come in three styles – outline, solid, and mini.
By default, the outline style is used, but solid and mini may
be applied by using the `-solid` and `-mini` suffix.
You can customize the size and colors of the icons by setting
width, height, and background color classes.
Icons are extracted from your `assets/vendor/heroicons` directory and bundled
within your compiled app.css by the plugin in your `assets/tailwind.config.js`.
## Examples
<.icon name="hero-x-mark-solid" />
<.icon name="hero-arrow-path" class="ml-1 w-3 h-3 animate-spin" />
