Custom template with full width bootstrap carousel

Hi, I want to make a custom page template with full width slider. How can I do that?

I know I can remove the container class in base.php and add it manually in my custom template file. When I do that every page works except the single posts page won’t show properly. Any help in the right direction would be appreciated.

I’ve read/tried other methods on google discussions and here about full witdth , but no success.
