[css-images-4] image-set 1x equivalence

[jonathantneal]

Would an image-set() with a single 1x image be equivalent to not using image-set() to begin with? Or is there a scenario where a browser should not meet the 1x threshold?

header {
  background-image: image-set(url("image@1x.png") 1x);
}

In other words, presuming the above code, is there a scenario where a browser supporting image-set would not attempt to use image@1x.png?

Yes.

image-set() never fails to choose an image; the <resolution> just helps determine which of the images is chosen. (And then affects determining the intrinsic size from the pixel width/height.)

Thank you, @tabatkins ! That resolves my issue. Closing!
