Require or disallow whitespace after the // in //-comments

a {
  width: 10px; // inline-comment
/*               ↑
 * Such whitespace */

The fix option can automatically fix all of the problems reported by this rule.

This rule only works with SCSS-like single-line comments and ignores CSS comments (/* */).

Any number of slashes are allowed at the beginning of the comment. So /// comment is treated the same way as // comment.

Note that a newline is not possible as a whitespace in terms of this rule as //-comments are intended to be single-line.
