@dreyks Thanks for your offer! We're always happy for contributions. 😄

I am planning to take a look at this issue in the next few days, starting by providing an API for users to re-run the polyfill on demand. It's a bit tricky because the polyfill makes changes directly to the original source CSS, so re-running it isn't as simple as just doing the same thing again. But I have some ideas of how to address this. (Then later hopefully we can also add an observer or something so that the polyfill itself can re-run intelligently.)

In this case it would be helpful if you could share the HTML/JS code you're trying to run -- that way as I work on it I can test directly against your use-case (and add it to the demo page).

thx for the response!

i'm doing this on a closed-source ui library, i'll try to craft a simplified example

meanwhile, I've moved the definition of anchorFunctions outside of parseCSS here so that it is maintained between polyfill invocations and now everything seems to be working, but i'm not sure it's the most performant solution 😂

here's an example (i realized I forgot how to write DOM-oriented JS without React 😂 )

it shows text hints depending on if it's polyfilled or native

@dreyks Apologies for the delay here, I've needed to focus on other projects for the past month or so. I still hope to get to this feature before too long, but in the meantime contributions are welcome if you (or anyone) is motivated to submit a PR! 😄

Any updates on this? Seeing how Chrome will land CSS Anchor Positioning, in May, would be great to have this issue solved :)

@lucsoft I agree! 😅

I'm hoping to spend some time on this in April, but honestly we could also use help from the community. Code contributions are welcome, as well as financial support (especially from companies that plan to use this in production).

Any movement here? Can't really use the polyfill in my angular application without it

@goodwinchris We'd love to make this happen! Financial support (especially from companies that plan to use this in production) will be key to getting this done.

In the meantime, you may be able to use it, depending on your use case. If you are able to detect when the anchor and positioned element are both in the dom, you can call the polyfill manually, and it should detect them. Here's an example in React- #283 (comment). If you're able to get it working in Angular, please post the code to help others! Thanks!
