Thanks for your help so far.
I added some services using the service post type. The headers are the same font / colour as the text. In your demo, the headers for each service stand out which looks far better. I can’t see how to change this. I put the headers in the title area when creating a new service post so surely it should automatically format it based on Sydney’s style.css?
