As I see you using Firefox so it might cause the `:has` selector is not working on your side. It’s only supported from Firefox 121.

> **["has" | Can I use... Support tables for HTML5, CSS3, etc](https://caniuse.com/?search=has)**
>
> "Can I use" provides up-to-date browser support tables for support of front-end web technologies on desktop and mobile web browsers.
