Div not taking height of parent div (w/ bootstrap) - html

Question

I'll start off by stating that I know this question has been asked a lot, but none of the answers I saw seemed to work for me.
Basically, I have some divs inside of a larger div. They'll have dynamic text, so I don't know how many lines each will be. The problem is that I can't seem to get the divs to size themselves to the parent's height. I want the column divs to take up the entire height of the row div (basically, I want that blue part to fill all the space between the bars).
HTML:
<div class="container">
<div class="row divOne">
<div class="col-xs-3 divTwo">Some Text</div>
<div class="col-xs-3">
Some text that could wrap to multiple lines
</div>
</div>
<div class="row divOne">
<div class="col-xs-3 divTwo">Different Text</div>
<div class="col-xs-3 divThree">
With some more text
</div>
</div>
</div>
CSS:
.divOne
{
border-top:10px solid black;
}
.divTwo
{
background-color: #32649b;
height:100%;
color:white;
}
jsfiddle:
Now, what I've learned from other versions of this question are that
float:left might be screwing it up
height:100% doesn't work if the parent's height is defined
position:relative might help on the parent
The problem with the float is that I'm using bootstrap, and that's where the float is coming from, so I don't really want to mess with that.
I can't really define parent height, because it'll be dynamic based on the children.
I also tried messing around with position:relative on the parent and absolute on the child, but that seemed to get really screwy. I'm also guessing this won't work because I'm using bootstrap. It's possible that I'm just missing something, though. I'll admit to not being the greatest with CSS.
I don't know if I'm having these issues because I'm using bootstrap, or because I'm just being an idiot right now.
Something else that seems to be throwing a wrench into things: These columns will be laid out differently on smaller screens vs. larger ones. I actually want something along the lines of col-xs-12 col-md-3 for these.

Answer 1

The short answer is that you can't really achieve this within the constraints of the bootstrap framework. There are plenty of articles that explain why div elements can't stretch to the height of their container, and how to get around this problem. One of the solutions I'm most fond of is Faux Columns.
But, let's get a little more creative then that.
I came up with something that might work for your scenario, but requires a bit of change to your markup. Here's a solution that wraps the bootstrap grid with display: table.
http://jsfiddle.net/Wexcode/13Lfqmjo/
HTML:
<div class="table-container">
<div class="table-row divOne">
<div class="col-xs-3 divTwo">Some Text</div>
<div class="col-xs-3">
Some text that could wrap to multiple lines
</div>
<div class="col-xs-6"></div>
</div>
</div>
CSS:
.table-container {
margin: 0 -15px;
}
.table-row {
display: table;
width: 100%;
}
.table-row [class^="col"] {
display: table-cell;
padding: 0 15px;
float: none;
}
Note that for this solution to work, you must include enough col elements to stretch it all 12 columns (see that I added an empty .col-xs-6 div).

Answer 2

You can add
display:flex;
to divOne , and will act like you wanted.
in bootstrap 4 'row' class applies this on div, but in ealier versions you need to add manually if you expect such behavior.

Answer 3

Give .divOne a display: flex and remove the height: 100% from .divTwo:
.divOne
{
border-top:10px solid black;
display: flex;
}
.divTwo
{
background-color: #32649b;
/*height:100%;*/
color:white;
}
