After building a page we can make sure it is up to standards by validating it with an HTML validator.
Web pages can be validated by many different validators available online.
A common validator can be found at: http://validator.w3.org/.
1. Click on the Validate by File Upload tab and then click on the browse button.
2. Navigate to your Edshare folder, or where ever the file is located and select the index.htm or other HTML file you want to check.
3. Click on the Check button to continue the validation.
The validator will return information on whether the page is valid or the errors that prevent it from validating correctly with descriptions.
