+
+## At-Rules
+
+`_media`, `_supports` and `_container` take a record of queries to styles. A query can also sit in the key itself, as in Emotion, and `globalCss` accepts at-rules around whole selector maps.
+
+```tsx
+const example = (
+  <Box
+    _media={{ '(min-width: 500px)': { p: 2 } }}
+    selectors={{ '@media print': { display: 'none' } }}
+  />
+)

+globalCss({
+  _motionReduce: { '*, *::before, *::after': { transition: 'none' } },
+})
+```
+
+Conditions always win over breakpoint values: at-rule styles come after every responsive rule. Among themselves they are ordered by condition, with width queries mobile-first (`min-width` ascending, then `max-width` descending), then media types, other features, and user preferences such as `prefers-*` last.
