madmoizo has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-anchor-position-1] Support for dynamic styling such as box-shadow based on position-try ==
I've been experimenting with `@position-try` and `position-try-fallbacks`, and noticed that some CSS properties aren’t valid descriptors within the current positioning system.
In my use case, adapting visual styles like `box-shadow` dynamically based on the chosen position (top, bottom, etc.) is required.

1. Would it be possible to allow new style descriptors inside `@position-try` blocks?

2. If not, is there an alternative-native approach to apply CSS styles conditionally, depending on the resolved `position-try-fallback`?
