Right way to embed variable google font Rubik

Question

I'm tring to import Rubik's all variations but I've some issue. I would like to have all rubik's variation in the same url (italic and weight) and according with this google's article and this from css-triks I wrote my url using periods and this seem to work if I import only weight's axis

https://fonts.googleapis.com/css2?family=Rubik:[email protected]&display=swap

but when I add the italic axis to url google return me "400 error: missing font family"

https://fonts.googleapis.com/css2?family=Rubik:ital,[email protected],400..900&display=swap

It seem like italic doesn't have all variation though the Rubik's type tester allow to use italic.

So what I'm doing wrong?

I would have all rubik's variation (italic and weight) in the same url. I've wrote the url following the instructions in a google fonts's article but it doesn't work.

Answer 1

Apparently, the ital feature currently requires two load 2 font files.

Maybe related to the fact, it provides only 2 values:
0 (off/normal) and 1 (on/italic)
So it's not a real design axis providing interpolated values like the similar slnt (slant) axis.

However you can use this URL:
https://fonts.googleapis.com/css2?family=Rubik:ital,wght@0,300..900;1,300..900

I highly recommend this post:

– it also contains a list of google font URLs

fontWeight.addEventListener('input', e=>{
  preview.style.fontWeight= +e.currentTarget.value;
})

ital.addEventListener('input', e=>{
  let fontStyle = e.currentTarget.checked ? 'italic' : 'normal';
  preview.style.fontStyle= fontStyle;
})
