How to keep the bottom height fixed for this code snippet

Here's what I'm trying to do:

<html>
<head>
    <style>
    body, html {
       width: 100%;
       height: 100%;
       margin: 0;
       padding: 0;
    }
    body {
       display: -webkit-flexbox;
          display: -ms-flexbox;
                display: flex;
       -webkit-flex-direction: column;
          -ms-flex-direction: column;
             flex-direction: column;
    }
    #stage {
       width: 100%;
       height: calc(100% - 65px);
       background: #BAD;
    }...
