css - Bootstrap 4, how to make a col have a height of 100%?

Question

how can I make a column take up 100% height of the browser w bootstrap 4?

See the following: https://codepen.io/johnpickly/pen/dRqxjV

Note the yellow div, I need this div/column to take up a height of 100%... Is there way to make this happen without having to make all parent div's have a height of 100%?

Thank you

html:

<div class="container-fluid">
  <div class="row justify-content-center">

    <div class="col-4 hidden-md-down" id="yellow">
      XXXX
    </div>

    <div class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8">
      Form Goes Here
    </div>
  </div>
</div>

Answer 1

Use the Bootstrap 4 h-100 class for height:100%;

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">
    <div class="col-4 hidden-md-down" id="yellow">
      XXXX
    </div>
    <div class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8">
      Form Goes Here
    </div>
  </div>
</div>

You'll also need ensure any parent(s) are also 100% height (or have a defined height)...

html,body {
  height: 100%;
}

Note: 100% height is not the same as "remaining" height.
