JS.VUE.HTML.COMMENT.CONTENT.SPACING

Rule Details

This rule will enforce consistency of spacing after the <!-- and before the --> of comment. It also provides several exceptions for various documentation styles.

Whitespace after the <!-- and before the --> makes it easier to read text in comments.
