设置两个div之间的div高度

Question

我正在尝试获取一个 div 高度，占用两个 div 之间的剩余空间。

<div id='company_col' class='contact_columns'>
  <div id='company_title' class ='col_title'>
	  <h3>Company</h3>
	</div>
  <hr>
  <div id='company_list' class='contact_lists'>
  </div>
  <div id='company_edit_bar' class='edit_bar'>
    <div id='company_add_btn' class='edit_btn'>
	    <i class='fa fa-plus' aria-hidden='true'></i>
	  </div>
  <div id='company_delete_btn' class='edit_btn'>
	  	<i class='fa fa-minus' aria-hidden='true'></i>
  </div>
</div>

这里是 JS 小提琴：https://jsfiddle.net/xqLpqsdk/

我需要制作 .contact_lists 来填充 .col_title 和 .edit_bar 之间的空间，因此滚动条只显示在这 2 个 div 之间

我尝试将 .contact_lists 位置设为绝对位置，但没有奏效。
