Page footer
About
There is not mouch going on in the #page-footer other than setting a background color and a top border. Use the Bootstrap container classes and populate it.
In the example below we are using the .container-md container to follow the #main-container width along with some padding for styling.
The content consists of a simple .row and .col system with some responsive text alignment.
Example
<footer id="page-footer"> <div class="container-md py-3 px-5"> <div class="row"> <div class="col-sm-6 py-1 text-center text-sm-start">Footer Content Left</div> <div class="col-sm-6 py-1 text-center text-sm-end">Footer Content Right</div> </div> </div> </footer>
