Detect support for @page with Vanilla JS
I need to determine whether a browser supports CSS’ @page rule or not…
I first thought that I may be able to do this easily with CSS’ @supports() rule. But my understanding now is that you cannot nest one rule in another and are only able to check the support of classic property/ value declarations.
Now I am trying to use vanilla JS to detect support:
if ('CSS' in window && CSS.supports('@page')) { ... } However, this always returns false regardless of browser support.
Does anyone know an alternative way that I can accurately test client support for CSS’ @page using vanilla JS?
TY.
