Web Standards

It is really hard to have a certain definition for Web Standards. In my opinion, Web Standards help to ensure that everyone can access the web, especially makes easily to use for people with special needs and also make sure the standardization and unified for the web. Those standards are important for both developers and users.

There are some web standards, such as ISO standards and Ecma, but I think  in most people's minds web standards is W3C. W3C is about make standards about web page building languages, they are HTML, XHTM ,CSS and DOM 1.

W3C standards tried to expand the reach of web in the following aspects.

• Everyone:It means however the cultural, language, abilities the users are, the users still can use the same web page.
• Everything: It is about the web pages and applications on web that the developers developed can be use in any kind of devices. It can use range from high processing computer to mobile devices. 
• Everywhere：No mater the speed of internet environments are high or low, the web pages still work no differences.
• Diverse mode of interaction: It is about use different ways to communicate between users and webpages, such as touch-pad, pen, mouse, voice etc. 
• Enable computer to do more useful work: It could achieve this feature through advanced data searching and sharing.

Accessibility is also a very important thing in web standards. It not only means to allow disabilities people, but also ensure the web page could use in different browsers and devices.
