About HTML Validator

Online HTML validator is a webool that checks the HTML (Hypertext Markup Language) code of a web page to ensure that it conforms to the official HTML specifications and standards defined by the World Wide Web Consortium (W3C). The W3C sets the standards for HTML, and these standards dictate how web pages should be structured and formatted to ensure consistency and compatibility across different web browsers and devices.

HTML validators are used to identify and report any errors or issues in the HTML code of a web page. These errors could include:

  • Missing or improperly nested HTML tags.
  • Incorrect attributes or values within HTML tags.
  • Deprecated or obsolete HTML elements.
  • Structural issues that could impact the accessibility or usability of a web page.
  • Incomplete or improperly closed tags.
  • Incorrect usage of character encoding.

By running HTML code through our HTML validator, web developers and designers can ensure that their code follows best practices and is more likely to display correctly and consistently across different browsers and devices. It can help improve the quality, accessibility, and search engine optimization (SEO) of a website.
