+# at-rule-semicolon-newline-after
+
+Require a newline after the semicolon of at-rules.
+
+```css
+@import url("x.css");
+@import url("y.css");
+/** ↑
+ * The newline after these semicolons */
+```
+
+This rule ignores `@import` in Less.
+
+This rule allows an end-of-line comment followed by a newline. For example:
+
+```css
+@import url("x.css"); /* end-of-line comment */
+
+a {}
+```
+
+## Options
+
+`string`: `"always"`
+
+### `"always"`
+
+There *must always* be a newline after the semicolon.
+
+The following patterns are considered violations:
+
+```css
+@import url("x.css"); @import url("y.css");
+```
+
+```css
+@import url("x.css"); a {}
+```
+
+The following patterns are *not* considered violations:
+
+```css
+@import url("x.css");
+@import url("y.css");
+```
+
+```css
+@import url("x.css"); /* end-of-line comment */
+a {}
+```
+
+```css
+@import url("x.css");
+
+a {}
+```
