Nesting Media Queries

No. You need to use the and operator and write that as two queries. You can, however, do this in SCSS, which will compile to CSS, but it will combine them by unfolding them and using the and operator.

This is a common problem, and once I first wrote LESS or SCSS, I didn’t ever want to go back to writing this long-hand.

Long-handed CSS:

@media (-webkit-min-device-pixel-ratio: 2) and (max-width: 768px) and (min-width: 320px),
                  (min-resolution: 192dpi) and (max-width: 768px) and (min-width: 320px) {
  body {
    border: 1px solid red;
  }
}
@media (-webkit-min-device-pixel-ratio: 2) and (max-width: 320px),
                  (min-resolution: 192dpi) and (max-width: 320px) {
  body {
    border: 1px solid blue;
  }
}

Nesting queries may work, but support varies across browsers.
