Full page width Blog and Pages

I saw some other topics for this but i can not get those solutions to work, i am looking to have my blogs and pages full width. I am not using any side bar content and would like the main content to widen out a bit more. Is there any additional css i can paste in to the editor?

Been thought the style sheets and not coming up with a solution

Hi there,
Thanks for reaching out.
In relation to your question here, could you kindly provide us with your website link.

I look forward to your reply.
Best Regards,

the website is hidden (under construction) at the moment while the content is being put together, but I have attached a screen shot of what it looks like full screen on a 1920x1080 screen

I am looking to make the section with the the text and galleries wider

HI there

The page on the screenshot is without sidebar, there is no more option in the theme to make it wider, for this custom css is necessary, so, i guess we need to see your website for custom css
