Module adds helpers for swithing locales in templates. For display flags it uses https://github.com/lipis/flag-icon-css from CDN. Before useing ensure that you included in app.html styles for countries flags:

stylesheet(“https://cdnjs.cloudflare.com/ajax/libs/flag-icon-css/2.7.0/css/flag-icon.css”)

For custom styling it use defined class with overloaing styles located after cdn styles;

Example:

iex> locales(@conn, [:us, :ru])

<span class="flag-icon-us flag-icon-background flag-icon"></span>

<span class="flag-icon-ru flag-icon-background flag-icon"></span>

It renders list of links without wrapper for customization purpose.
