Hi @ Creedon, thanks for your reply, appreciate it, but this method creates a site wide change, whereas I'm looking to target the Blog Post page only. My aim is to have the blog landing pages with full colour backgrounds:
https://www.traceyjohnson.work/graphic-design-portfolio https://www.traceyjohnson.work/photography-portfolio
And internal blog post pages to remain white:
https://www.traceyjohnson.work/retouching-portfolio/racq
With my template, using the Design > Site Styles method I am limited as colour changes are site wide rather than page by page. As a work around I've entered custom code into the Blog Settings > Advanced > Page Header Code Injection section to be able to change the Header, Intro & Main background colours, which is great for the Blog main page, but it colours the internal pages:
https://www.traceyjohnson.work/graphic-design-portfolio/milque
I'm trying to find a way to get these internal blog pages to remain white, or find another custom code to change them to white.
Attached is the custom code I've used.
