Sunsetting Quirks Mode. Apparently proper standards support in IE (or at least the IE8 renderer) will be triggered by the HTML5 doctype, providing an alternative to those who don’t wish to pollute their markup with an IE-specific meta tag. # 23rd January 2008, 2:56 pm
If Web authors actually use this feature, and if IE doesn’t keep losing market share, then eventually this will cause serious problems for IE’s competitors — instead of just having to contend with reverse-engineering IE’s quirks mode and making the specs compatible with IE’s standards mode, the other browser vendors are going to have to reverse engineer every major IE browser version, and end up implementing these same bug modes themselves.
Like DOCTYPE switching did in 2000, version targeting negates the vendor argument that existing behaviors can’t be changed for fear of breaking web sites. If IE8 botches its implementation of some CSS property or DOM method, the mistake can be fixed in IE9 without breaking sites developed in the IE8 era. This actually makes browser vendors more susceptible to pressure to fix their bugs, and less fearful of doing so.
Beyond DOCTYPE: Web Standards, Forward Compatibility, and IE8. This has huge implications for client-side web developers: IE 8 will include the ability to mark a page as “tested and compatible with the IE7 rendering engine” using an X-UA-Compatible HTTP header or http-equiv meta element. It’s already attracting a heated debate in the attached discussion. # 22nd January 2008, 12:40 pm
