+# at-else-empty-line-before
+
+Require an empty line or disallow empty lines before `@`-else.
+
+```scss
+@if ($a == 0) { }
+                      /* ← */
+@else if ($x == 2) { }   ↑
+                         ↑
+/**                      ↑
+ * This empty line */
+```
+
+`@if` and `@else` statements might need to have different behavior than all the other at-rules. For that you might need to set `"ignoreAtRules": ["else"]` for stylelint's core rule [`at-rule-empty-line-before`](http://stylelint.io/user-guide/rules/at-rule-empty-line-before/). But that would make you unable to disallow empty lines before `@else` while forcing it to be on a new line. This rule is designed to solve exactly that.
+
+## Options
+
+`string`: `"never"`
+
+There is no `"always"`, `"always-single-line"` options, because for such cases stylelint's `at-rule-empty-line-before` would work.
+
+### `"never"`
+
+There *must never* be an empty line before `@else` statements.
+
+The following patterns are considered warnings:
+
+```scss
+@if ($x == 1) {
+  // ...
+}
+
+@else {}
+```
+```scss
+@if ($x == 1) {
+  // ...
+} @else if ($x == 2) {
+  // ...
+}
+
+
+@else { }
+```
+
+The following patterns are *not* considered warnings:
+
+```scss
+@if ($x == 1) {
+  // ...
+} @else if ($x == 2) {
+  // ...
+} @else {}
+      
+a {
+  @if ($x == 1) {
+    // ...
+  }
+  @else ($x == 2) {
+    // ...
+  }
+}
+```
