Possible disadvantages of W3C Markup Validation Service

  • Limited to Syntax
    The validator primarily checks for syntax errors and does not assess other vital web development aspects such as design or functionality.
  • Outdated Standards
    The tool relies on W3C's standards, which can sometimes lag behind real-world usage and popular web development trends, potentially limiting its relevance.
  • Overly Strict
    The validator can be overly strict, flagging non-critical issues that may not impact user experience but are still considered 'errors' by the tool.
  • Misinterpretation of Results
    Less experienced developers might misinterpret the validator's results, focusing too much on achieving perfect validation without understanding the real impact on usability.
  • Lack of Support for Modern Frameworks
    As a markup validator, it might not fully support or correctly evaluate modern JavaScript frameworks that generate markup dynamically.

    Looking at the html of HN's pages, can't blame them really. Running though https://validator.w3.org/ , the result is abysmal.
