Diisplay flex not stretching a div - html

Question

I used CSS property display: flex. My content div's are not equal.
right now it looks like:
I want to make it look like so:
HTML
<div class="poplar-boxes">
<div class="popular-boxes-devider"></div>
</div>
<div class="poplar-boxes">
<div class="popular-boxes-devider">
</div>
CSS
.poplar-boxes {
display: flex;
justify-content: space-between;
flex-wrap: wrap;
align-items: stretch;
}
.popular-boxes-devider {
flex-basis: 30%
}
Here is a JS Fiddle

Answer 1

Your flex item are the same in height ( popular-boxes-devider ) . The problem is that you set the border to .info which are not equal in height.
The trick is to get them equal. You need to calculate their height depending on their margin top, padding and height of the round circle above them
See snippet below
/* Added styles */
.effect2,
.icon {
height: 100%;
}
.info {
height: calc(100% - 72px);
box-sizing: border-box;
}
.popular-boxes-devider {
margin-bottom: 15px;
}
/* end Added styles */
.poplar-boxes {
min-height: 100%;
display: flex;
justify-content: space-between;
flex-wrap: wrap;
}
.popular-boxes-devider {
flex-basis: 30%;
}
