Duplicated page no loading the same

Hi,
I hope someone might be able to help me with this. My website https://www.haylockpittman.co.uk. has a custom made home page which I want to replicate. I have duplicated the page, but when I load the new page it does not load the 2 main images next to each other.
On looking closer the main page calls div id “outer” which is 950px but the internal page calls the same div id and shows it as 600px.
I looked at the style sheet and it appears that it is calling extra div id’s for the home page such as .home .outer but I would like to know what I need to do to the style sheet to get the same layout on an internal page.
Below is the style sheet and the .home call ups start on line 960.
Thanks
