Changing "boxed layout" of CB default template to "full-width" layout.

Config:
Joomla 3.6.2, Helix 3 Framework Joomla template based on Bootstrap (fully responsive), CB default template with override.css (Nick's/Kyle's "example" thing).

Between header and footer of my Joomla template all content (e.g. CB) goes into a component area (full 12 bootstrap grid) which is set to fluid (full width).
However CB appears in "boxed layout". Experimenting with CB's template column layout did not do the job at all.

How do I get a full-width layout?

Thx. Michael.

Don't understand what you mean by boxed layout. Please provide a screenshot of your issue.

Hello,

here are 2 screenshots, where the first demonstrates how a CB profile renders in a full-width template setting.
CB sits in a 1x12 grid row (full-width), which is no problem for non-CB content items taking all the width.

Second shot shows coding of page. As you can see, there are left and right margins around CB.
When I set these margins to 0 or the inner content box to a large px-size, the boxed layout gets wider.
However this disturbs the responsiveness of CB's profile page (does not render correctly when sm devices..

I wonder which parameters I'd have to modify to get CB "full-sized" spreading whole page.

Thanks a lot in advance.

That wouldn't have anything to do with CB. We've no specific width values set. It'll fill whatever width is available. Right click and inspect the page to review its CSS.
