# declaration-block-trailing-semicolon Require or disallow a trailing semicolon within declaration blocks. ```css a { background: orange; color: pink; } /** ↑ * This semicolon */ ``` The trailing semicolon is the *last* semicolon in a declaration block and it is optional. This rule ignores: - Less mixins - trailing `//` comments - declaration blocks containing nested (at-)rules The `--fix` option on the [command line](../../../docs/user-guide/cli.md#autofixing-errors) can automatically fix all of the problems reported by this rule. ## Options `string`: `"always"|"never"` ### `"always"` There *must always* be a trailing semicolon. The following patterns are considered violations: ```css a { color: pink } ``` ```css a { background: orange; color: pink } ``` ```css a { @include foo } ``` The following patterns are *not* considered violations: ```css a { color: pink; } ``` ```css a { background: orange; color: pink; } ``` ```css a { @include foo; } ``` ### `"never"` There *must never* be a trailing semicolon. The following patterns are considered violations: ```css a { color: pink; } ``` ```css a { background: orange; color: pink; } ``` The following patterns are *not* considered violations: ```css a { color: pink } ``` ```css a { background: orange; color: pink } ```
