Bootstrap grid with 3 divs in a row with same height

Question

I have 3 Div-Container inside a row. Each one has, caused by the content, a different height. I want to set background color, but the color should reach to the bottom of the parent-Div (Row). All my tries failed, I wont get the same height of the divs.

<div class="row">
  <div class="col-md-7">Test</test>
  <div class="col-md-2">Test</test>
  <div class="col-md-3">Test</test>
</div>

With a table it will be easy, but thats not the state of the art...

What will be the css-style for do that, if I wont to support responsive layout?

What version of Bootstrap you are using? The approach for this will be setting a fixed height to the `row` and then `100%` height for all the `col` children. **Bootstrap 4** have some utilities classes for this... If you specify the Bootstrap version I will show you an example. — Shidersz, Dec 14 '18 at 21:43
adding a fix height, is not so pretty, if i have smaler devices, i lost unused space in same divs. — StefB, Dec 14 '18 at 21:46
You could apply the rules only on medium or large devices using a `media query` in that case. I will come with an example later if you still accept having a fixed height on the `row` for **md** screens and above. — Shidersz, Dec 14 '18 at 21:49
year setup for different devices will be a way to do i think :-) — StefB, Dec 14 '18 at 21:57

For Bootstrap 3 versions, you could approach a fixed height for md+ screen devices (width >= 992px) with something like this:

@media(min-width:992px) {

    .fixed-md-height {
        height: 150px;
    }
    
    .h-100 {
        height: 100%;
    }
}

<div class="container-fluid">
  <div class="row fixed-md-height">
    <div class="col-md-7 h-100 bg-danger">Test</div>
    <div class="col-md-2 h-100 bg-primary">Test</div>
    <div class="col-md-3 h-100 bg-warning">Test</div>
  </div>
</div>

On Bootsrap 4 there already exists a built-in class h-100, but the md breakpoint changes to width >= 768px. So the approach will be something like this:

@media(min-width:768px) {

    .fixed-md-height {
        height: 150px;
    }
}

<div class="container-fluid">
  <div class="row fixed-md-height">
    <div class="col-md-7 h-100 bg-danger">Test</div>
    <div class="col-md-2 h-100 bg-primary">Test</div>
    <div class="col-md-3 h-100 bg-warning">Test</div>
  </div>
</div>

@bootstrap3 have a define generaly height for .fixed-md-height and/or h-100? — StefB, Dec 14 '18 at 22:35
For what I know, I will say no, but i'm not `100%` sure. Note that `fixed-md-height` is just a custom class I have made. So, do this approach work for your goals? — Shidersz, Dec 14 '18 at 22:38
