IE8 uses multi-compatibility mode to display web pages normally
|
IE8 will have multiple compatibility modes . IE platform architect Chris Wilson wrote in his blog that the job of the IE platform is to provide both interoperability (web pages can work properly in different browsers) and backward compatibility (compatible with previous versions of IE browsers). If IE8 is to remain compatible with the billions of current web pages while also meeting the goal of making development for billions of future web pages easier, IE8 will use a different mode to display web pages. He said in his blog that in the development of the past six major versions of IE browser, the principle was "not to break the existing WEB (rules)". In IE6, they used the DOCTYPE switch to switch between different "modes" to ensure compatibility. In IE7, they modified more parts of IE to make it more compliant with standards, especially improving compatibility with CSS. Many people have said that there are many problems when using IE6 browser to open certain sites, but they are normal with Firefox and Safari browsers, and they display normally in IE7. In fact, IE7 was released in 2006, while IE6 was released in 2001. The network standards that IE followed during its development were the standards at the time. So, the exact meaning of "don't break the existing web" is "don't change any pages that developers have already deployed and that display normally in the current IE" (of course, some standards may not be deployed yet, so don't expect things to happen in the future) Therefore, in the IE8 browser, the development team used multiple compatibility modes to be compatible with previous web pages. The first two modes are: "Quirks" mode, which is compatible with most current web content. "Standards" mode, also known as "standards mode", is compatible with content that IE7 can display normally. The third mode requires the cooperation of web developers. Web developers need to add an additional meta tag to the web page to identify their own web page in order to achieve the best compatibility with IE8. It is reported that in "standard mode", IE8 can pass the very strict Acid2 page test. |
