CSS background image not displaying in Codepen

Hi all.
I have my Personal Portfolio project ready to submit. Everything works fine on my local machine.
When I transferred the code to Codepen to submit it and relinked the images as Codepen assets, the background image does not show, and all the other CSS is broken.
Has anybody any ideas?
I cannot put the link to Codepen in here as this is my first post here, but it if you search for stephencox1971 you can find it.

Kind Regards,

Stephen.

I only see a survey pen not a portfolio.

I don’t see your personal Portfolio project. :confused:

My apologies. Should be visible now.

Thanks very much, that works perfectly.
