Mobile Web Tools

W3C have a number of tools to help with designing web pages for mobile phones and other portable devices:

• W3C mobileOK Basic Tests 1.0, W3C Working Draft 13 November 2006,
• "Mobile Web Best Practices 1.0 - Basic Guidelines", 2 November 2006
• W3C Mobile Web Best Practices checker (ALPHA).

The checker tests you web page and reports problems. But make sure you are using proper XHTML first, using the W3C Validator.
