Are window.screen.width and height returned values in CSS pixels or actual screen pixels?

问题

From the API name screen and from this DOC link, I would expect them to be actual screen size pixels.

https://developer.mozilla.org/en-US/docs/Web/API/Screen/width

But from the tests I've run so far, it seems they return CSS pixels.

• 360 for window.screen.width for my Galaxy A5 (both on Chrome and Firefox)

• 768 for window.screen.width for my iPad (both on Chrome and Safari)

Which are CSS pixel values.

QUESTION

Is this consistent across browsers? Can I trust I'll always get CSS pixel values?

回答1:

I found the confirmation that it is in CSS pixels in the CSS spec.
