Is the trigger Pageview only valid on the home page?

For Workes & Pages, what is the name of the domain?

What is the issue or error you’re encountering

Pageview

What steps have you taken to resolve the issue?

For example, I add a Custom HTML that triggers a Pageview , adding a test red div on the screen. But I only see the red div on https://wangyifang.com/. I can’t see the red div on PCSS. Why?
