html - Bootstrap : Unable to center contents of entire row

问题描述

I'm learning HTML5, CSS3 and Bootstrap4 and have created a dummy project.

I'm attempting to create a row that will house my icon and text (company name) side-by-side and have use display:inline to achieve the same. This is followed by a tag line.

However I'm unable to get the content of the entire row in the center. I have tried text-center or text-xs-center but to no avail. I even created a custom css class 

.text-center-custom{
    text-align: center !important;
}

but that also didn't work.

justify-content-center作为row 参考，您可以通过Bootstrap 4 flex 实用程序 希望它会有所帮助
