Fix & Workaround

Inline all CSS directly in the HTML.

Before

<head>
  <link rel="stylesheet" href="styles.css" />
</head>

After

<head>
  <style>
    /* Paste your CSS here, or use a build tool like
       juice/inline-css to inline automatically */
    .container { max-width: 600px; margin: 0 auto; }
    .header { background-color: #6d28d9; padding: 32px; }
  </style>
</head>

Inline all CSS instead of using external stylesheets
