                <div class="m-4">
  <h1 class="text-xl">Basic validation check</h1>
    In this example, the input field is revalidated on each key press (the 'input' event).
  <form class="flex flex-col gap-3 align-self-end max-w-xs rounded-lg p-4 bg-stone-200" novalidate>
    <p class="error text-red-800"></p>
    <input type="text" required class="bg-slate-50">
    <button class="self-end bg-cyan-800 text-white px-4 py-1">Submit</button>


                p:empty { 
  display: none;


                const form = document.querySelector('form');
const error = document.querySelector('.error');
const input = document.querySelector('input');

form.addEventListener('submit', event => {
  // Stop the form submission so we don't leave CodePen!

// Revalidate on each keypress once the field has changed 
input.addEventListener('input', event => {
  // Clear out any previous error.
  error.textContent = '';
  // Trigger the validation check. If the input field is invalid, it will emit an
  // 'invalid' event.

input.addEventListener('invalid', event => {
  // Even with the novalidate attribute the form still
  // gives us a suitable error message; we just have to display it
  // ourselves.
