+# declaration-block-semicolon-space-after
+
+Require a single space or disallow whitespace after the semicolons of declaration blocks.
+
+```css
+a { color: pink; top: 0; }
+/** ↑
+ * The space after this semicolon */
+```
+
+This rule ignores semicolons that are preceded by Less mixins.
+
+This rule ignores the last semicolon of declaration blocks. Use the `block-closing-brace-*-before` rules to control the whitespace between the last semicolon and the closing brace instead.
