Split a div inside bootstrap vertically - html

Question

I'm struggling with a rather simple task but the lack of CSS experience is getting the better of me:
<div class="row">
<div class="col-lg-3">
<div class="ibox-content m-b-sm border-bottom">
<div class="ibox-title">
<span class="label label-info pull-right">Offline</span>
<h5>Equipment Pass</h5>
</div>
<div class="ibox-content">
<h1 class="no-margins">#Model.AirportPassEquipmentOffline.TransactionCount</h1>
<small># of Transactions</small>
</div>
</div>
</div>
<div class="col-lg-3">
<div class="ibox-content m-b-sm border-bottom">
<div class="ibox-title">
<span class="label label-success pull-right">Online</span>
<h5>Equipment Pass</h5>
</div>
<div class="ibox-content">
<h1 class="no-margins">#Model.AirportPassEquipmentOnline.TransactionCount</h1>
<small># of Transactions</small>
</div>
</div>
</div>
<div class="col-lg-3">
<div class="ibox-content m-b-sm border-bottom">
<div class="ibox-title">
<span class="label label-info pull-right">Offline</span>
<h5>Visitor Pass</h5>
</div>
<div class="ibox-content">
<h1 class="no-margins">#Model.AirportPassVisitorOffline.TransactionCount</h1>
<small># of Transactions</small>
</div>
</div>
</div>
<div class="col-lg-3">
<div class="ibox-content m-b-sm border-bottom">
<div class="ibox-title">
<span class="label label-success pull-right">Online</span>
<h5>Visitor Pass</h5>
</div>
<div class="ibox-content">
<h1 class="no-margins">#Model.AirportPassVisitorOnline.TransactionCount</h1>
<small># of Transactions</small>
</div>
</div>
</div>
</div>
Above is a row on my view. There are many like it:
I want to split the smallest div to show a second Heading1. Here is base HTML:
<div class="ibox-content">
<h1 class="no-margins">#Model.AirportPassEquipmentOffline.TransactionCount</h1>
<small># of Transactions</small>
<h1 class="no-margins">#Model.AirportPassEquipmentOffline.Income</h1>
<small>Income generated</small>
</div>
Target:
I need to show more information and I see that the div card is empty on the right side. I want to split this div into two. Experimenting with bootstrap classes, the layout breaks.

Answer 1

Afer a bit of trial and error, i realized that the small grid class was the issue. I switched to class-md and got the desired result. So this:
<div class="ibox-content">
<h1 class="no-margins">#Model.AirportPassEquipmentOffline.TransactionCount</h1>
<small># of Transactions</small>
<h1 class="no-margins">#Model.AirportPassEquipmentOffline.Income</h1>
<small>Income generated</small>
</div>
Became this:
<div class="ibox-content">
<div class="row">
<div class="col-md-6">
<h1 class="no-margins">#Model.AirportPassEquipmentOnline.TransactionCount.ToString("N0")</h1>
<small># of Transactions</small>
</div>
<div class="col-md-6">
<h1 class="no-margins">AED #Model.AirportPassEquipmentOnline.Income.ToString("N2")</h1>
<small>Revenue generated</small>
</div>
</div>
</div>
