At the international webmasters association (IWA), we are doing our best to create one web for all, which looks the same under every electronic device with internet access.
More information about our mission can be found here: http://www.w3.org/Consortium/mission
There are a few key elements, you need to consider in order to create a web compatible product:
- Web standards
- UTF-8
- Javascript independency (don’t forget the NOSCRIPT tag)
- tableless (CSS based) layout
- high contrast between the background and the font colours
- use screen fonts (serif or sans-serif)
