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

问题

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>

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.

I have tried over a half-dozen solutions suggested on Stack Overflow, and the only thing that worked for me was this:

<div class="row" style="display: flex; flex-wrap: wrap">
    <div class="col-md-6">
        Column A
    </div>
    <div class="col-md-6">
        Column B
    </div>
</div>

I got the solution from https://codepen.io/ondrejsvestka/pen/gWPpPo

Note that it seems to affect the column margins. I had to apply adjustments to those.

Set display: table for parent div and display: table-cell for children divs

HTML :

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

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

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

CSS:

#yellow {
  height: 100%;
  background: yellow;
  width: 50%;
}
#red {background: red}

.container-fluid {bacgkround: #ccc}

/* this is the part make equal height */
.display-as-table {display: table; width: 100%;}
.display-as-table > div {display: table-cell; float: none;}

Although it is not a good solution but may solve your problem. You need to use position absolute in #yellow element!

#yellow {height: 100%; background: yellow; position: absolute; top: 0px; left: 0px;}
.container-fluid {position: static !important;}

I solved this like this:

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

                <article className="d-flex flex-column justify-content-center align-items-center vh-100">
                        <!-- content -->
                </article>

            </div>
    </section>
