Here is the code that effectively aligns the text in the middle:
<div class="container section-content">
<div class="row" style="border-radius: 4px; border: solid 1px #979797;">
<div class="col-md-3 align-self-center" style="background-color: #4a90e2">
Align
</div>
</div>
</div>
The current output can be viewed here: https://i.sstatic.net/avEB2.png However, the desired output should fill the entire left column with the background color.
How can I achieve this?
