Children of table-cell bootstrap columns not occupying full height

Question

I have 3 different account cards with varying content in each card. I want all the cards (which reside inside a col-md-4 class) to occupy the full height of the column.

I gathered from [this][1] thread that one way to achieve that is to use display: table. The main issue is that I have a div inside the my columns which I need to occupy the full height of the column. I set those divs to display: inline-block and height to 100% but divs seem to be behaving as if height was set to auto and not occupying full height

Here is my html:

    .container {
    	display: table;
    }

    .row {
    	display: table-row;
    	height: 100%;
    }

    .col-md-4 {
    	display: table-cell;
    	float: none;
    	height: 100%;
    }

   

    .account {

		background: $overlay-color;
		text-align: center;
		display: inline-block;
		margin: 0;
		padding: 0;
		height: 100%;

    }

Answer 1

Try with flexbox

.container {
    display: table;
}
.row {
    display: flex;
}
.col-md-4 {
    float: none;
}
.account {
	background: rgba(0, 0, 0, 0.34);
	text-align: center;
	display: inline-block;
	margin: 0;
	padding: 0;
	height: 100%;
}
