The height of two divs equal based of height of main div

I have two divs on my page; side panel and main panel.

In the side panel I will always have a bunch of blocks on content, the number with change all the time. And the main panel will have some block of content. Generally the side panel will have bigger height than main panel.

I am looking for the main panel height to equal the content in that panel and I am looking for a way to have the height of the side panel equal to the size of the main panel. While the the overflow of the side panel scroll. Im not looking to set a static height for either, because the amount of content changes.

Currently I'm using grid but all for changing that if there is a way to do this.

Here is a Codepen mockup of what I currently have: https://codepen.io/aculbreth/full/VMjRyx

.box {
  display: grid;
  grid-template-columns: 1fr 4fr;
  grid-gap: 20px;
  grid-auto-columns: max-content;
  background: #efefea;
  margin: 50px auto;
  padding: 20px;
  box-sizing: border-box;
  .side_panel {
    background:#fff;
    padding:20px;
    box-sizing: border-box;
    .side_panel_box {
      text-align:center;
      border: 1px solid #000;
      margin-bottom:20px;
    }
  }
  .main_panel {
    background:#fff;
    padding:20px;
    box-sizing: border-box;
    display:block;
    grid-auto-columns: max-content;

  }
}

Here is a rough mockup of what i'm looking for: enter image description here

As you've tagged your post with jQuery, it can be done via jquery pretty painlessly. As your CSS was questioned, I remade it to be simple css, and the jQuery simply sets the side pane height to the main content height. Hope it helps!

*** Please note, to see either of these work well, view them full-page.

$(document).ready(function() {
  var maxHeight = $(".main_panel p").height();
  $(".side_panel").height(maxHeight);
})
.box {
  display: grid;
  grid-template-columns: 1fr 4fr;
  grid-gap: 20px;
  grid-auto-columns: max-content;
  background: #efefea;
  margin: 50px auto;
  padding: 20px;
  box-sizing: border-box;
}

.side_panel {
  background: #fff;
  padding: 20px;
  box-sizing: border-box;
  overflow: auto;
}

.side_panel_box {
  text-align: center;
  border: 1px solid #000;
  margin-bottom: 20px;
}

.main_panel {
  background: #fff;
  padding: 20px;
  box-sizing: border-box;
  display: block;
  grid-auto-columns: max-content;
}

Doing the same thing in pure CSS, here's the following. Note that this is applied pretty much directly from here, and applied to this particular use case.

.box {
  display: flex;
}

.flex-item {
  flex: 0 0 50%;
  position: relative;
}

.flex-item-inner {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  overflow: auto;
}

.side_panel {
  background: #fff;
  padding: 20px;
  box-sizing: border-box;
  overflow: auto;
}

.side_panel_box {
  text-align: center;
  border: 1px solid #000;
  margin-bottom: 20px;
}

.main_panel {
  background: #fff;
  padding: 20px;
  box-sizing: border-box;
  display: block;
  grid-auto-columns: max-content;
}
<div class="box">
  <div class="flex-item side_panel">
    <div class="flex-item-inner">
      <div class="side_panel_box">
