Substitutions can have different outputs, reasons, and formatting applied to them to alter their display. By default the output is html and the formatting is none. So for example the below will DIV format a tab substitution.
[cb:usertab tab="11" formatting="div" /]
If you're using CB Bootstrap you need to surround the substitution with bootstrap templates CSS selector as it only styles it self to avoid styling outside of CB. Example as follows.
<div class="cb_template_bootstrap">[cb:usertab tab="11" formatting="div" /]</div>
