Utility First


Codice che avremmo dovuto usare:
 <head>
   ...
   <style>
      body {
        margin-top: 200px !important;
      }
      .alert {
        display: flex;
        max-width: 24rem;
        margin: 0 auto;
        padding: 1.5rem;
        border-radius: 0.5rem;
        background-color: #fff;
        box-shadow: 0 20px 25px -5px rgba(0, 0, 0, 0.1),
          0 10px 10px -5px rgba(0, 0, 0, 0.04);
      }
      .alert-logo-wrap {
        flex-shrink: 0;
      }
      .alert-logo {
        height: 3rem;
        width: 3rem;
      }
      .alert-body {
        margin-left: 1.5rem;
        padding-top: 0.25rem;
      }
      .alert-title {
        color: #1a202c;
        font-size: 1.25rem;
        line-height: 1.25;
        font-weight: 500;
      }
      .alert-message {
        color: #718096;
        font-size: 1rem;
        line-height: 1.5;
      }
    </style>
  </head>
  <body>
    <!-- HTML/CSS Version -->
    <div class="alert">
      <div class="alert-logo-wrap">
        <img class="alert-logo" src="../assets/img/warning.svg" alt="alert" />
      </div>
      <div class="alert-body">
