# block-closing-brace-newline-after

Require a newline or disallow whitespace after the closing brace of blocks.

```css
a { color: pink; }
a { color: red; }↑
/**              ↑
 * The newline after this brace */
```

This rule allows an end-of-line comment separated from the closing brace by spaces, as long as the comment contains no newlines. For example,

```css
a {
  color: pink;
} /* end-of-line comment */
```

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 */  
}
```
