Do you use Markup Validation Service to check your HTML and XHTML code?
Markup Validation Service allows you to check your web page against the W3C recommendations. When developing web pages you want to create a clean and valid web page. It makes it easier for someone else to read and add new parts to a web page. Every web language like HTML has its own syntax it must follow in order to produce a clean and valid web page, Markup Validation Service allows you to achieve that goal.
Go to Markup Validation Service:
- Enter the URL or upload file to check
- Review the results and make changes to fix errors
