slider size problem

This is what I want if i didn’t make myself clear https://demo.themetor.com/official/demo1/

Can you provide the link to check the exact problem ? Revolution slider is used in this theme. You can define the size and full width option in slider settings. Hope this could help you.

thank you very much for your help. i do appreciate that. the link is not useful because i didn’t apply what i want, still. lets say i want to do it in any new theme.
look at this link https://demo.themetor.com/official/demo1/ and see how the picture slider is full width from both sides and how the header and footer are only in the middle.
