Gradual loading

[maranmaran]

What is the expected behavior?

Possibility to allow for array of images of different qualities and let them load in order background: url(high-res), url(low-res) || background: url(low-res), src=url(high-res)

example fiddle: https://jsfiddle.net/45uaLenw/1/

What is the current behavior?

We can only provide single URL?

What is the use-case or motivation for changing an existing behavior?

Faster loading of lower-res images but allowing for higher-res load over time - better UX
