使用flex布局解决部分浏览器下max-height一直出现滚动条

<div class="container">
  <div class="header">Header without specific height. Always stays at top of .container, even if it is so long it uses up two lines.</div>
  <div class="content">
    <div>Item no 1 in long list</div>
    <div>Item no 2 in long list</div>
    <div>Item no 3 in long list</div>
    <div>Item no 4 in long list</div>
    <div>Item no 5 in long list</div>
    <div>Item no 6 in long list</div>
    <div>Item no 7 in long list</div>
    <div>Item no 8 in long list</div>
    <div>Item no 9 in long list</div>
    <div>Item no 10 in long list</div>
    <div>Item no 11 in long list</div>
    <div>Item no 12 in long list</div>
  </div>
</div>
