I haven't found a suitable solution to this and it seems so trivial.
I have two columns inside a row:
<div class="row">
  <div class="col-xs-9">
    <div class="left-side">
      <p>sdfsdf</p>
      <p>sdfsdf</p>
      <p>sdfsdf</p>
    </div>
  </div>
  <div class="col-xs-3">
    <div class="something">asdfdf</div>
  </div>
</div>
The row height is set by the larger row, left-side. However, I want the right side's height to be the same.
This seems intuitive, but it doesn't work
.left-side {
    background-color: blue;
}
.something {
    height: 100%;
    background-color: red;
}
.row {
    background-color: green;
}
