website to open in my header and footer

Please re-explain what you mean by “in the skin of my website”.

here is a demo of my site…

https://www.bristolbikeexchange.co.uk/website

I need the page to open in my header and footer so I guess the ‘main’ section is where the website opens.

At the moment it leaves my site and goes to the other site.

The reason I want to do this is because I am working with the other company so the user needs to be able to use his website but within my environment.

So i need to keep my menu and my footer.

Sounds like you’ll need to extensively manipulate your theme, you can contact your theme’s vendors here: https://themeforest.net/user/JoinWebs

Oh I thought it would be as simple as telling a link to open in the ‘Main’ section
