Set div to remaining window height

Question

I'm trying to create a simple website that has a Header containing the logo and other information, then a ribbon as separator and then a two-column section. Left column will have a selector. Right column will have information depending on the option chosen on the selector.

I was able to do this so far but now I wanna take it to the next level. I would like my site to always fit to the window so no vertical scrollbar needed. I'm comfortable with the sizes of my header and ribbon so I want the two-column section to take the remaining space in the window. The scrollbar, if needed, would be on the information div. Just in case, I want the left-half (selector) to take as much space as it needs. Right-half (information) should adjust to the space it has left.

I have this code so far:

CSS

.container {
    display: table;
    width: 100%;
}

.left-half {
    display: table-cell;
    background-color:#7ec0ee;
}
.right-half {
    display: table-cell;
    overflow: auto;
}

HTML

<div id="header" style="background-color:#7ec0ee; padding-top:20px; padding-left:5px; padding-bottom:20px" align="center">
    <div id="header-logo" align="left">
        <img src=".." alt="MDN" width="160" height="113">
    </div>
</div>
<div id="black-banner" style="background-color:black; padding:2px">&nbsp;</div>
<div id="container" class="container">
    <div class="left-half">
        <select>..</select>
    </div>
    <div id="content" class="right-half"></div>
</div>

I suggest using flex. It's fantastic for responsive designs. You can set the width in the flex property on your left or right halwes.

.container {
  display: flex;
  width: 100%;
  height: calc(100vh - 98px); //98px is the height of your header
}

.left-half {
  flex: 1;
  background: red;
}

.right-half {
  flex: 1;
  padding: 1em;
  overflow: auto;
  background: blue;
}

<div id="header" style="background-color:#7ec0ee; padding-top:20px; padding-left:5px; padding-bottom:20px" align="center">
  <div id="header-logo" align="left">
    <img src=".." alt="MDN" width="160" height="113">
  </div>
</div>
<div id="black-banner" style="background-color:black; padding:2px">&nbsp;</div>
<div id="container" class="container">
  <div class="left-half">
    <select>..</select>
  </div>
  <div id="content" class="right-half"></div>
</div>

This might work for you. you can make use of the calc function in CSS.

.container {
    display: flex;
    width: 100%;
    height: calc(100vh - 100px); //Replace this 100px with whatever value elements other than container are occupying
}

.left-half {
  width:50%;
  background-color:#7ec0ee;
}
.right-half {
    background: red;
    width: 50%;
}
