It doesn't follow the same coding logic as the majority of the site, and IMHO, needs to be entirely overhauled or thrown out.
From what I can see, Bootstrap is not currently supported for BBCode within PHP Fusion 9. which makes it difficult to use Responsive div/class types within things like the forum and comments.
On other pages such as articles and news, I can use code for images and videos and make them responsive by using code such as:
<center><img class='img-responsive' src='URL' alt='LABEL'></center>
<div class='embed-responsive embed-responsive-16by9'><iframe class='embed-responsive-item' src='youtube url'></iframe></div>
Are there any plans to bring Bootstrap functionality into BBCode Land?
