IE7 CSS Changes

Category: IE

<p>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 – though we may try out new features in the future using the official –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 “quirks mode” as it has been established since IE6.

Read about the many changes that have been made.

An IE 7 Cheat Sheet has been released

So how much work will it require to update my site to fix IE7 quirks

IE7 RC1 is now available. Please upgrade your IE7 install and give it a spin. http://blogs.msdn.com/ie/archive/2006/08/24/715752.aspx

I’d rather not have another release of IE and have 6 be the final version. Sort of like IE 5 for mac. This is just going to be another headache because we have another browser to deal with and it will have a large user base fairly quickly.

Whether you like IE7 or not, the communication by the dev has been very nice. The argument that IE6 should be the final version sounds like a very bad idea to me, because if IE7 will be adopted quickly that will save us a lot of css hacks. And if there was no progress then when will we get things like local storage, transparent png support, canvas support etc…

I am looking forward to CSS2 compliance. Developing for people using IE is completely frustrating when everything looks better in FF ;-)

[...] Le blog Ajaxian pointe vers un billet du blog des développeurs de IE7 qui annonce qu’ils vont beaucoup mieux respecter les standard de l’Internet (souvent pilotés par le W3C). [...]
