Designing a blogpage

Hi,
I am doing the blogpages, and I would like a look similar to the pages to create consistency in the design.

Here is my first try: https://onlinemarketingbureauet.dk/facebook/facebook-live-streaming/

As you can see it's not full width like a normal page here: https://onlinemarketingbureauet.dk/sociale-medier/facebook-annoncering/

I have set it to full width in blogpage element, but it's not full width.

What can I do about it ?

Thanks
