+# block-closing-brace-space-after
+
+Require a single space or disallow whitespace after the closing brace of blocks.
+
+```css
+a { color: pink; }
+/** ↑
+ * The space after this brace */
+```
+
+This rule allows a trailing semicolon after the closing brace of a block. For example,
+
+```css
+:root {
+ --toolbar-theme: {
+ background-color: hsl(120, 70%, 95%);
+ };
+/* ↑
+ * This semicolon */
+}
+```
