"Linux.com looks at several web development tools. 'Of all the Web development programs in this list, Nvu is the only one that really does a lot 'behind the scenes.' With the other programs, you're not very far removed from the actual code, so whether it's standards-compliant is up to the user rather than the program. Nvu generates the code for you, so it's important to consider the code that it generates and whether it's up to snuff. Nvu has a validation tool that submits a page to the World Wide Web Consortium (W3C) Markup Validation Service, and the code generated by Nvu doesn't always pass.'"
