Are simple @media {} declarations supported?

[ryanleichty]

Under the @media section on caniemail it lists the following note:

[4] Partial. Does not support simple @media {} declarations

However, the citation note [4] is not listed under any of the browsers. Does anyone know if simple @media {} declarations are generally supported, or do you need to use the screen media type like this @media screen and {} in media query declarations?

I'm mainly curious because that's how Tailwind outputs media queries by default (e.g., @media (min-width: 640px)).
