html - How to center content in a bootstrap column?

Question

I am trying to center column's content. Does not look like it works for me. Here is my HTML:

<div class="row">
   <div class="col-xs-1 center-block">
       <span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
   </div>
 </div>

Answer 1

Use:

<!-- unsupported by HTML5 -->
<div class="col-xs-1" align="center">

instead of

<div class="col-xs-1 center-block">

You can also use bootstrap 3 css:

<!-- recommended method -->
<div class="col-xs-1 text-center">

Bootstrap 4 now has flex classes that will center the content:

<div class="d-flex justify-content-center">
   <div>some content</div>
</div>

Note that by default it will be x-axis unless flex-direction is column
