I successfully added @tailwindcss/custom-forms to my Elixir Phoenix project.

However it seems that any form-* style class don't add some styles or add none at all.

How I use
I created a new input/2 function that have this custom classes basic-form*, as:

defmodule Conts.InputHelpers do
  @moduledoc """
  Define <%= input f, :pass, type: :password_input %> syntax
  to create dynamic form inputs
  """

  use Phoenix.HTML

  alias Phoenix.HTML.Form, as: PhxForm
  import ContsWeb.ErrorHelpers, only: [error_tag: 2]

  @label_opts "basic-form-label"
  @input_opts "basic-form-input"

  def input(form, field, opts \\ []) do
    label_text = opts[:label] || humanize(field)
    type = opts[:type] || PhxForm.input_type(form, field)

    label_opts = [class: @label_opts]
    input_opts = [class: "#{@input_opts} #{state_class(form, field)}"]

    label_opts = if opts[:id], do: [for: opts[:for]] ++ label_opts, else: label_opts

    content_tag :fieldset do
      label = label(form, field, label_text, label_opts)
      input = input(type, form, field, input_opts)
      error = error_tag(form, field)

      error = if Enum.empty?(error), do: "", else: error

      [label, input, error]
    end
  end

  defp state_class(form, field) do
    cond do
      # The form was not yet submitted
      !form.action -> ""
      form.errors[field] -> "border-red-500"
      true -> "border-blue-500"
    end
  end

  # Implement clauses below for custom inputs.
  # defp input(:datepicker, form, field, input_opts) do
  #   raise "not yet implemented"
  # end
  defp input(:password_confirmation, form, field, input_opts) do
    apply(PhxForm, :password, [form, field, input_opts])
  end

  defp input(type, form, field, input_opts) do
    apply(PhxForm, type, [form, field, input_opts])
  end
end

Maybe can be a newbie error from my part but I'm not getting how to debbug or solve this issue.

Actually, in the reproduction repository it worked! But I'm not getting how I could debug my original application!

To make the reproduction repository works you need:
Elixir: > 1.7
Phoenix: 1.5.8
yarn: 1.22.10

Steps:

1. Clone repo
2. mix do deps.get, deps.compile
3. yarn --cwd assets
4. mix ecto.setup
5. mix phx.server

I just deleted alll priv/static/css,priv/static/js and assets/node_modules/.cache/hard-source folders and recompiled all project and it worked gracefully.

Thanks!
