defmodule Corex.Action do
  @moduledoc """
  Renders a button element for actions based of Phoenix Core Components.
  Use the `type` attribute to set the button type.
  Icon-only buttons must pass `aria_label` to screen readers.

  ## Examples
    ```elixir
    <.action>Send!</.action>
    <.action phx-click="go">Send!</.action>
    <.action type="submit">Save</.action>
    <.action aria_label="Close dialog">
      <.icon name="hero-x-mark" aria-hidden="true" />
    </.action>
    ```

  ## Styling

  If you wish to use the default Corex styling, you can use the class `button` on the component.
  This requires to install `Mix.Tasks.Corex.Design` first and import the component css file.

  ```css
  @import "../corex/main.css";
  @import "../corex/tokens/themes/neo/light.css";
  @import "../corex/components/button.css";
  ```

  You can then use modifiers

  ```heex
  <.action class="button button--accent button--lg">
  ```
