Standards-Compliant Authoring Tools

HTML-Kit is a full-featured, low priced editor designed to help HTML, XHTML and XML authors to edit, format, lookup help, validate, preview and publish web pages. Validation is done with HTML Tidy, so you can verify standards compliance.

Updates to older versions for standards compliance:
Some caveats: It appears that tools currently available from Namo generate IE-specific or Netscape 4-specific code that may require extra debugging for compatibility with standards-based browsers. Newer versions of Microsoft FrontPage™ have improved, however be sure not to rely on FrontPage-specific extensions for critical website content or functionality. Some versions of Microsoft Word create invalid HTML code that only works with Internet Explorer. Always be sure to validate your web pages.
