Show HN: Super simple rough notes in 37lines of HTML

An even simpler implementation is possible if you don't want tab support, bold/italics:

    <html contenteditable="true" autofocus></html>
    <script>
 const a = localStorage.getItem("saved-content");
 document.querySelector("body").innerHTML = a;
 setInterval(() => {
  localStorage.setItem("saved-content", document.querySelector("body").innerHTML);
 }, 2000);
    </script>
