@LostKobrakai has already done this in his blog and has open sourced the approach.

LostKobrakai/kobrakai_elixir/blob/main/lib/kobrakai_web/views/blog_html.ex

defmodule KobrakaiWeb.BlogHTML do
  use KobrakaiWeb, :html

  embed_templates "blog_html/*"

  def index(assigns) do
    ~H"""
    <div>
      <h2 class="uppercase mb-6"><%= @page_title %></h2>
      <div class="sm:columns-2 lg:columns-3">
        <ol class="-my-4">
          <KobrakaiWeb.PageHTML.list_item
            :for={{p, index} <- @posts |> Enum.reverse() |> Enum.with_index()}
            class={"opacity-0 animate-in animation-fill-mode-forwards animation-delay-#{index * 55}"}
            headline={p.title}
            date={p.date}
            tags={p.tags}
            url={~p"/kolumne/#{p.id}"}
          />
        </ol>
