redimensionar elemento com conteúdo html

<style>
  .grow-with-content { min-width: 200px; width: fit-content; }
</style>

<body>
  <div class="grow-with-content" contenteditable="true">
    The quick brown fox jumped over the lazy dog.
  </div>
</body>

<!--
also works if you're doing plain css code and you have it linked to html
