Html Validator: Ensure Web Standards with Error Detection

An HTML validator is a software tool that checks HTML code for errors and issues to ensure it meets web standards. It scans HTML documents to detect malformed code, invalid markup, and other problems.

What is HTML Validator?

An HTML validator is an essential tool for web developers to test and validate HTML code. It analyzes HTML documents and detects issues such as:

  • Malformed HTML tags and attributes
  • Improper code nesting
  • Missing closing tags
  • Deprecated tags and attributes
  • Accessibility issues

Using an HTML validator helps ensure web pages meet modern standards set by the W3C (World Wide Web Consortium) and web browsers. This improves consistency in how pages are displayed across different devices and browsers.

There are many free online HTML validators available such as the W3C Markup Validation Service, Nibbler, and HTML5 validator. Some IDEs and text editors also include built-in validation features. The validator scans code and highlights errors, warnings, and general issues. It provides helpful feedback to debug and fix code.

Validating HTML is an important step in development to improve quality. It helps avoid potential rendering issues and ensures accessibility for the visually impaired using screen readers. Clean, valid HTML also improves SEO through better crawlability, indexing, and page ranking.
