Bootstrap 4 row fill remaining height

问题:

I'm struggling to make the a row stretch to fill the rest of the available height. I tried adding h-100 to the row class but that causes a white space at the bottom of the screen. There must be a way to do it but I'm totally stumped.. Here is my code:

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">
    <div class="col-4 bg-red">
      <div class="h-100">
        <div class="row justify-content-center bg-purple">
          <div class="text-white">
            <div style="height:200px">ROW 1</div>
          </div>
        </div>
        <div class="row justify-content-center bg-blue">
          <div class="text-white">ROW 2</div>
        </div>
      </div>
    </div>
    <div class="col-8 bg-gray"></div>
  </div>
</div>

I'd like to make the the blue row (ROW 2) fill all the red space. Any suggestions?

Thanks

Use the Bootstrap 4.1 flex-grow-1 class...

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">
    <div class="col-4 bg-red">
      <div class="h-100 d-flex flex-column">
        <div class="row justify-content-center bg-purple">
          <div class="text-white">
            <div style="height:200px">ROW 1</div>
          </div>
        </div>
        <div class="row justify-content-center bg-blue flex-grow-1">
          <div class="text-white">ROW 2</div>
        </div>
      </div>
    </div>
    <div class="col-8 bg-gray"></div>

Make the container a flex-box with a column direction (.d-flex.flex-column) and give row 2 the .col class to make it expand vertically:

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">
    <div class="col-4 bg-red">

      <!-- these classes here -->
      <div class="h-100 d-flex flex-column">
        <div class="row justify-content-center bg-purple">
          <div class="text-white">
            <div style="height:200px">ROW 1</div>
          </div>
        </div>

        <!-- adding col adds the style flex-grow: 1 -->
        <div class="row justify-content-center bg-blue col">

          <div class="text-white">ROW 2</div>
        </div>
      </div>
    </div>
    <div class="col-8 bg-gray"></div>
  </div>
</div>
