this is the code that works actually 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>
but this is the output:
 the desired output should fill the whole left column with the background color.
the desired output should fill the whole left column with the background color.
how do i achieve this?
