css div 布局排放问题

<div class="box">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
</div>
样式: 
 .box {
      height: 202px;
      width: 202px;
      border: 1px solid red;
    }
    .item {
      height: 100px;
      width:  100px;
    }

一个大div里有4个小的div, 想要让4个小div 纵向排列, 达到大的div高度时,能自动换行, 如何用CSS实现? 想要的效果: 成2列,每列2个div
