我有一个容器，它有一个头标签和一个div。div会消耗剩余的空间，因为容器的高度为100VH。在div中还有两个div，一切正常，但当我向右侧的div添加更多内容并缩小浏览器窗口时，它会溢出父div，我使用了flex box，所以它应该包装内容，而原始div的高度应该相应增加以包装它的元素，但它没有发生。

HTML：

    <div class="holder">
     <h1>Work Slides</h1>
     <div class="slides">
     <div class="slide-image">
      <img src='' alt=''>
     </div>
     <div class="slide-content">
      <span>Image Name</span>
      <div>
        Lorem, ipsum dolor sit amet consectetur adipisicing elit. Illo, magni eos nam in suscipit ex reiciendis, ea repellat cumque minus amet maiores ipsam dolorum dolore mollitia. Architecto eos adipisci blanditiis.

      </div>
    </div>
  </div>
</div>
<span>Page-2</span>

CSS：

*{
  box-sizing: border-box;
}
html,body{
  margin: 0;
}
.holder{
  height: 100vh;
  max-height: 100%;
  background: royalblue;
  display: flex;
  flex-direction: column;
  align-items: center;
}
.slides{
  background: palevioletred;
  display: flex;
  justify-content: center;
  width: 100%;
  flex-wrap: wrap;
  height: 100%;
}
.slide-image, .slide-content{
  max-height: 400px;
  background: orange;  
}
.slide-image img{
  height: 100%;
  width: 400px;
  max-width: 100%;
}
.slide-content{
  width: 400px;
  padding: 2%;
  display: flex;
  flex-direction: column;
}

我在这里做错了什么？是最小-最大高度/宽度吗？
