What is the “W3C” standard?

“W3C standards” means standards of W3C standards approved by the Working Group on the final stage of the process. The name of the document that the standard has gone through W3C member organizations and the public’s review, which aims to standardize Web technology. So far, W3C has developed more than 50 specification (draft). In the Firefox, Google teamed up to launch the W3Help website (http://www.w3help.org/zh-cn/), the on HTML, CSS, DOM specifications do more description.

Why do we need “W3C” standard?

Currently popular on the Internet in a variety of browsers, the browser dealing with a same page, sometimes differences in performance or behavior. If this is very different, may result in some browsers can not view the website. Problems caused by these differences is “browser compatibility issues.”

Browser mode is often referred to as “rendering mode.” Different browsers render mode is not only an impact analysis on the code and script behaviors are also affected. If a page can make the browser work in “standard mode”, then the browser will be “standard” approach, making Internet users when using a different browser, see little difference between the page. Conversely, if a page so that all browsers are working in “mixed mode”, then the browser will be the difference between the performance of a very large impact of Internet users browsing experience.

Therefore, Internet developers in the preparation of a page, should be used to trigger the browser to the “standard model” of the DTD, and writing compliant code, to ensure the web in all browsers for maximum compatibility, for the users to bring better browser experience. This “standard” is “W3C” advocated “W3C” international standard.

Consequences of the fact that the standard brewing over the benefits of common standards

Back in early 2009, there had been 2,400 sites and domestic IE8 incompatible phenomena, spared many famous sites, the Chinese site is almost completely annihilated. The reason is the majority of sites in accordance with the W3C standard is not compatible with older versions of IE were caused by the development.

Microsoft on August 27, 2001 Published IE6 (Internet Explorer 6), enhance the compatibility of CSS1, making analytical and IE6 on the CSS before rendering and it has a very different version of IE5.5. In order to maintain good backward compatibility, Microsoft provides the user with a “switch” to determine the browser mode. In the subsequent launch of IE7, IE8, also used the “switch.” Thus, making IE7, IE8 and IE6, as in the “mixed mode” on page processing. Therefore, IE series of “hybrid model” the behavior of the browser to freeze in the old version of IE5.5 browser. As time advances forward and standards, this “hybrid model” can not adapt to the rapid development of the Internet.

In China, because Windows bundled with IE browser, they have caused the IE (especially IE6) wide application. The majority of sites in accordance with national standards are not compatible with older versions of IE for development, when the IE browser upgrade, the emergence of a number of domestic sites are not compatible with the phenomenon. In particular aspects of the web of silver, because the domestic most banks provide only Windows and IE-based online payment solutions, resulting Zhong Duofei Windows, non-IE users Wufazhengchang login online banking, pairs of users of Internet use causes terrible harm.

With Firefox browser users share continued to rise, the Firefox browser has been sit tight in the global market, number two. It is in the majority of users and non-IE users, the call to a third party payment platform, “Alipay” never support Firefox and other non-IE browser to fully support cross-platform online payment, users needs to win the “standard dispute, “an important battle. The Shanghai Pudong Development Bank, one of the Big Four state-owned China Construction Bank has also announced support for Firefox. Adhere to international conventions of the “W3C” standard, users will be more convenient Internet browsing.

“W3Help” website to help developers understand the Chinese Internet standards, to improve the compatibility issues

Firefox has consistently adhered to internationally accepted standards in the early Firefox3.5, it is important to upgrade brought online media, providing the world’s first video and audio support HTML5 implementation (Ogg Vorbis and Ogg Theora, allowing Web developers page contains rich media content, and you can use JavaScript, HTML, CSS to manipulate them. the Firefox and Google join forces once again, released W3Help website ((http://www.w3help.org/zh-cn /), for domestic developers to provide more “W3C” standard introduction to the causes of compatibility, compatibility issues and provide concrete examples of reference for web developers, Internet users in China to enhance the Web experience to contribute!
