Flex box - 扭曲时溢出问题

Question

让我来解释一下这个问题。

假设我们有 2 个 flex box boxOrange 和 boxPurpule 共享容器的整个宽度并拉伸到这个容器的高度。由于它们的 min-width of 400px，这些 flex box 在小屏幕上扭曲 'column'（示例 1 中的演示）。

如果其中一个框包含太多内容，则该框是可滚动的（如示例 2 的演示中的 boxOrange）。

问题是它们在小屏幕上是可滚动的内容。我希望 boxOrange 在变形时保留 container 的 50% height。正如您在示例 2 中看到的，boxOrange 的内容不可滚动并溢出 container.

你知道怎么解决吗？

Answer 1

如果你给 boxOrange 一个 max-height: 50% 它会滚动而不是增长

#container {
  background-color: red;
  padding: 10px;
  width: 80%;
  height: 300px;
  display: flex;
  flex-wrap: wrap;
  align-items: stretch;
}
#boxOrange {
  background-color: orange;
  flex: 1;
  min-width: 400px;
  overflow: auto;
}
#boxPurple {
  background-color: purple;
  flex: 1;
  min-width: 400px;
}

@media screen and (max-width: 1050px) {
  #boxOrange {
    max-height: 50%;
  }
  #boxPurple {
    height: 50%;
  }
}

Answer 2

@LGSon 提出的媒体查询的替代方案。

这个方案是用JS写的（withjQuery），不知道断点就好了

/* Modify layout */
jQuery(function($){
    
    var boxOrange = $("#boxOrange");
    var boxPurple = $("#boxPurple");
    
    var breakPoint  = parseInt(boxOrange.css('min-width')) + parseInt(boxPurple.css('min-width'));

    var container = $("#container");
        
        
    $(window).load(function(){
        setRowOrColumn();
        $(window).resize(setRowOrColumn);
   });
 
 
    function setRowOrColumn ()
    {
      if (container.width() < breakPoint && container.hasClass( "in_row" ))
      {
        container.removeClass("in_row");
        container.addClass("in_column");
      }
      else if (container.width() >= breakPoint && container.hasClass( "in_column" ))
      {
        container.removeClass("in_column");
        container.addClass("in_row");            
      }
    }
 
});

#container
{
  background-color:red;
  padding:10px;
  width:80%;
  height:300px;
  
  display: flex;
}

#container.in_row
{
  flex-direction:row;
}

#container.in_column
{
  flex-direction:column;
}

#boxOrange
{
  background-color:orange;
  flex:1;
  min-width:400px;
  overflow:scroll;
}

#boxPurple
{
  background-color:purple;
  flex:1;
  min-width:400px;
}
