Answer 1

I was facing the same problem in Bootstrap 4.1.0. Here is what I figured out:

I was doing this (having my paragraph inside div with class "row"):

<div class="container-fluid">
    <div class="row" style="background-color: #009688;">
       <p class="text-center" style="color: #fff;"> Meet me at</p>
    </div>
</div>

Later I removed the class and it worked.

<div class="container-fluid">
    <div style="background-color: #009688;">
       <p class="text-center" style="color: #fff;"> Meet me at</p>
    </div>
</div>
