defmodule Heroicons do
  @moduledoc """
  Provides precompiled icon compiles from [heroicons.com v<%= @vsn %>](heroicons.com).

  Heroicons are designed by [Steve Schoger](https://twitter.com/steveschoger)

  ## Usage

  Hero icons come in three styles – outline (`24x24`), solid (`24x24`), and mini (`20x20`).

  By default, the icon components will use the outline style, but the `solid` or
  `mini` attributes may be passed to select styling, for example:

  ```heex
  <Heroicons.cake />
  <Heroicons.cake solid />
  <Heroicons.cake mini />
  ```

  You can also pass arbitrary HTML attributes to the components:

   ```heex
  <Heroicons.cake class="w-2 h-2" />
  <Heroicons.cake solid class="w-2 h-2" />
  ```

  By default, the outlined (24x24) component is used, but the `solid` or `mini`
  attributes can be provided for alternative styles.

  You may also pass arbitrary HTML attributes to be applied to the svg tag.
