Some HTML is “Optional”
11.9.2019

Can you nest @media and @support queries?
5.8.2019
Yes, you can, and it doesn't really matter in what order. A CSS preprocessor is not required. It works in regular CSS.
This works:
@supports(--a: b) {
@media (min-width: 1px) {
body {
background: red;
}

}
And so does this, the reverse nesting of the above:
@media (min-width:...
