Flex box - overflow issue when warp

问题


Let's me try to explain the issue.

Assume we have 2 flex box boxOrange and boxPurpule who share the full width of a container and stretch to the height of this one. Due to their min-width of 400px, these flex box warp in 'column' on small screen (demonstration in Example 1).

If one of the box contain too much content, the box is scrollable (like boxOrange in the demonstration of Example 2).

The issue is when their is scrollable content on small screen. I would like the boxOrange keep 50% height of container when it warp. As you can see in Exemple 2, the content of boxOrange, isn't scrollable and overflow the container.

Do you know how to fix that ?

Example 1 - Available on codepen.io

#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: scroll;
}
#boxPurple {
  background-color: purple;
  flex: 1;
  min-width: 400px;
}
<div id=container>

  <div id="boxOrange">

  </div>

  <div id="boxPurple">
  </div>

</div>

Example 2 - Available on codepen.io

#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: scroll;
}
#boxPurple {
  background-color: purple;
  flex: 1;
  min-width: 400px;
}
<div id=container>
  <div id="boxOrange">

回答1:


If you give the boxOrange a max-height: 50% it will scroll instead of grow

#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%;
  }
}

An alternative to the media query proposed by @LGSon.

This solution is in JS (with jQuery), it's nice if the breakpoint is unknown

/* 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;
}
