如何调整段落的字体大小以填充flexbox容器中的项目高度？

<style>
  .container {
    display: flex;
    align-items: stretch;
    height: 200px;
    border: 1px solid #ccc;
  }

  .item {
    font-size: 20px;
    border: 1px solid #ccc;
    padding: 10px;
  }
</style>

<div class="container">
  <div class="item">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</div>
  <div class="item">Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</div>
  <div class="item">Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</div>
</div>
