Thursday, August 24th, 2006p>The IE Team has posted more details on the IE7 CSS changes so we can all get prepared:
We are currently locking down IE7 for shipping and I wanted to give an update on the CSS work that went into IE7. Chris originally outlined our plans for IE7, and we listened to a lot of feedback (blog, connect database, conferences, our WASP partnership etc.) to help us address the most grievous bugs and prioritize which features to put in for IE7. I like to thank especially the contributors on this blog for their participation. Your feedback made a difference in deciding what issues to address.
We understand that we are far from being done and we know we have still a lot of work ahead of us. IE 7 is a stepping stone in our effort to improve our standards compliance (especially around CSS). As an example, in the platform we did not focus on any proprietary properties â€“ though we may try out new features in the future using the official â€“ms- prefix, following the CSS extension mechanism. We also work very closely with the W3C CSS working group (which I am a member of) to help clarify assumptions in our implementation and drive clarifications into the spec. I really like to thank everyone who helped us here.
In all, we made over 200 behavior changes (bug fixes or new features) under strict mode to improve CSS2.1 compliance. All this work (with the exception of transparent PNGs) has been done under the <!DOCTYPE> switch only, since all changes required behavioral updates to be more in line what the CSS spec specifies. To preserve application compatibility we will not make any behavioral changes to â€œquirks modeâ€ as it has been established since IE6.
