　W3C summarized 10 basic rules from "Mobile Web Best Practices" :
Design consistent web pages for multiple devices. When designing mobile web pages, a variety of devices must be considered to reduce costs and increase flexibility.

Rely on web standards: In a market with a variety of devices, web standards can ensure compatibility between different devices. Avoid some common issues with mobile devices: no pop-ups, no nested tables, and no Frames. Be aware of the limitations of mobile devices: Mobile devices generally do not support technologies such as Cookies, Javascript, etc. Optimize navigation: Use a clear, concise, minimal navigation system. Check graphics and colors: Do not use high-resolution images. Check graphics based on the possible screen size, resolution, and supported colors and contrast of the mobile device to make sure they display properly. Be small: The page display size, file size, and CSS size should be as small as possible. Save bandwidth: Do not use automatic refresh, redirection and other technologies. Don’t reference too many external resources and make good use of page caching. To facilitate user input: The input method of mobile devices is very difficult to use, so it is necessary to provide convenient assistance for user input as much as possible. Consider busy users: Busy users have limited time, and the information provided by the mobile web should be concise and clear.
