I'm 100% sure but I think that I've seen the article about how you created this blog in Next.js. But I can't find it now. Did you delete it? Or it never existed and it was just How I Built My Blog that is in my browser history. Without the URL I can't look it up on archive.org.

There's a text in the navigation which indicates what section of the article we are currently reading. It works if we navigate directly to the article (e.g. permalink). However, when we change the article, instead of indicating our current place in the text, it displays the heading of the last viewed article.

Steps to reproduce:

1. Navigate to an article (e.g. https://typeofweb.com/typescript-infer-i-typy-warunkowe),
2. Use the top level navigation to display a list of articles (e.g. click JavaScript),
3. Open different article (e.g. https://typeofweb.com/react-hooks-wlasne-hooki);

Description:

As in title.

Solution:

Change css property 'z-index' value of banner or mobile menu.
