# double-slash-comment-empty-line-before Require or disallow an empty line before `//`-comments. ```scss a {} /* ← */ // comment /* ↑ */ /** ↑ * This line */ ``` The `--fix` option on the [command line](https://github.com/stylelint/stylelint/blob/master/docs/user-guide/cli.md#autofixing-errors) can automatically fix all of the problems reported by this rule. This rule only works with SCSS-like [single-line comments](https://sass-lang.com/documentation/syntax/comments) and ignores: * comments that are the very first nodes in a file; * CSS comments (`/* */`); * comments that are on the same line as some non-comment code (inline comments). ## Options `string`: `"always"|"never"` ### `"always"` There *must always* be an empty line before `//`-comments. The following patterns are considered warnings: ```scss a {} // comment ``` The following patterns are *not* considered warnings: ```scss a {} // comment ``` ```scss a {} // comment ``` ### `"never"` There *must never* be an empty line before `//`-comments. The following patterns are considered warnings: ```scss a {} // comment ``` The following patterns are *not* considered warnings: ```scss a {} // comment ``` ```scss a {} // comment ``` ## Optional options ### `except: ["first-nested", "inside-block"]` #### `"first-nested"` Reverse the primary option for `//`-comments that are nested and the first child of their parent node. For example, with `"always"`: The following patterns are considered warnings: ```scss a { // comment color: pink; } ``` The following patterns are *not* considered warnings: ```scss a { // comment color: pink; } ``` #### `"inside-block"` Reverse the primary option for `//`-comments that are inside a block. For example, with `"always"`: The following patterns are considered warnings: ```scss a { background: pink; // comment color: pink; } ``` The following patterns are *not* considered warnings: ```scss a { background: pink; // comment color: pink; } ``` ### `ignore: ["between-comments", "stylelint-commands", "inside-block"]` #### `"between-comments"` Don't require an empty line before `//`-comments that are placed after other `//`-comments or CSS comments. For example, with `"always"`: The following patterns are *not* considered warnings: ```scss a { background: pink; // comment // comment color: #eee; } ``` ```scss a { background: pink; /* comment */ // comment color: #eee; } ``` #### `"stylelint-commands"` Ignore `//`-comments that deliver commands to stylelint, e.g. `// stylelint-disable color-no-hex`. For example, with `"always"`: The following patterns are considered warnings: ```scss a { background: pink; // not a stylelint command color: #eee; } ``` The following patterns are *not* considered warnings: ```scss a { background: pink; // stylelint-disable color-no-hex color: pink; } ``` #### `"inside-block"` Ignore `//`-comments that are inside a block. For example, the following patterns are *not* considered warnings: ```scss a { background: pink; // comment color: pink; } ``` ```scss a { background: pink; // comment color: pink; } ```
