html - 没有垂直边框的动态内容高度

Question

几个小时后，我能够创建一个具有固定页眉、动态内容高度和始终位于(屏幕)底部的页脚的布局。这是代码:https://jsfiddle.net/r56oqg41/

html {
  height: 100%;
}
body {
  margin: 0;
  padding: 0;
  height: 100%;
  background: #DEDEDE;
}
#main {
  display: flex;
  min-height: 100%;
  flex-direction: column;
}
#head {
  width: 100%;
  height: 40px;
  border-bottom: 1px solid #115293;
  background-color: #1976D2;
}
#head #head_content {
  width: 600px;
  padding: 6px;
  color: #FFFFFF;
  margin: 0 auto;
  text-align: center;
}
#body {
  flex: 1;
  width: 600px;
  margin: 0 auto;
  background-color: #FFFFFF;
  border-left: 1px solid #BFBFBF;
  border-right: 1px solid #BFBFBF;
}
#body #menu {
  float: left;
  width: 150px;
  padding: 10px;
  background-color: #94C9FF;
  border-right: 1px solid #BFBFBF;
}
#body #page {
  overflow: hidden;
  padding: 10px;
  color: #5C5C5C;
}
#foot {
  width: 100%;
  height: 40px;
  color: #FFFFFF;
  border-top: 1px solid #115293;
  background-color: #1976D2;
}
#foot #foot_content {
  width: 600px;
  padding: 6px;
  margin: 0 auto;
  text-align: center;
}

<div id="main">
  <div id="head">
    <div id="head_content">
      HEADER
    </div>
  </div>
  <div id="body">
    <div id="menu">
      MENU
    </div>
    <div id="page">
      <p>PAGE CONTENT 01</p>
      <p>PAGE CONTENT 02</p>
      <p>PAGE CONTENT 03</p>
      <p>PAGE CONTENT 04</p>
      <p>PAGE CONTENT 05</p>
      <p>PAGE CONTENT 06</p>
      <p>PAGE CONTENT 07</p>
      <p>PAGE CONTENT 08</p>
      <!--
                <p>PAGE CONTENT 09</p>
                <p>PAGE CONTENT 10</p>
                <p>PAGE CONTENT 11</p>
                <p>PAGE CONTENT 12</p>
                <p>PAGE CONTENT 13</p>
                <p>PAGE CONTENT 14</p>
                <p>PAGE CONTENT 15</p>
                <p>PAGE CONTENT 16</p>
                <p>PAGE CONTENT 17</p>
                <p>PAGE CONTENT 18</p>
                <p>PAGE CONTENT 19</p>
                <p>PAGE CONTENT 20</p>
-->
    </div>
  </div>
  <div id="foot">
    <div id="foot_content">
      FOOTER
    </div>
  </div>
</div>

问题是菜单(或 #page)的垂直边框在没有内容时保持隐藏状态...

我不希望页脚总是固定在底部。这将取决于页面内容。

另一个问题是这个解决方案在 IE11(可能所有以下版本)中不起作用:(

请问有没有办法一直显示垂直边框？

谢谢!
