Center Column Content In Bootstrap - css

Question

I'm working on a project using Bootstrap 4. I have a row that consists of three columns. My code looks like this:
<div class="row">
<div class="col-md-4 center-block">
<div>
<i class="glyphicon glyphicon-time center-text"></i><br />
<h3>On Time</h3>
<h4>Just for you</h4>
</div>
</div>
<div class="col-md-4 center-block">
<i class="glyphicon glyphicon-star center-text"></i><br />
<h3>Excellent Service</h3>
<h4>When you need it</h4>
</div>
<div class="col-md-4 center-block">
<i class="glyphicon glyphicon-heart center-text"></i><br />
<h3>We want to be your favorite</h3>
<h4>Why not?</h4>
</div>
</div>
I need to center the content within each column. However, all of the content is left-aligned and I do not know why. As the code shows, I'm using the center-block and center-text classes. Yet, they do not seem to be working. What am I doing wrong?

Answer 1

You need to use text-center instead of center-block.
There is no default Bootstrap class such as center-text and the class needs to be used for the parent container, not along with any child element.
