IE7 and CSS (Score:5, Insightful) by Dr. Eric Peters (email@example.com) on 17-06-02 21:50 (#3718281) (User #586095 Info | (LINK)
Based on secondhand reports, it sounds to me as if IE7 is going to bring *major* advances in CSS support for Windows Internet Explorer. They're going to fix the box model, with bugwards compatibility handled via a DOCTYPE sniffing strategy similar to IE6/Mac's.
This is a hugely significant event for advocates of CSS. I'm eagerly looking forward to this, even though I don't plan on ever using Windows on a regular basis. Given Microsoft's ability to bulldoze Windows users into upgrading, we may soon have a world in which, for the first time ever, *the dominant Web browser* has good CSS support.
This could improve things for CSS in general even if we don't end up with the dreaded Microsoft-only world. Developers of *other* browsers will no longer be able to hide behind claims of industry-leader compatibility when releasing buggy CSS implementations.
Of course DOCTYPE sniffing is going to complicate the situation somewhat, since IE7 will still have a bugwards compatibility mode. I'm hoping that the existence of IE7 will cause enough people start intentionally invoking standards mode that other browser developers notice. While from a theoretical point of view DOCTYPE sniffing makes no sense--it's a pure hack--in practice it's a lot better than no standards mode at all, which is the only likely alternative.
Furthermore, my secondhand source also tells me that IE7 will finally bring full PNG support to IE. This is a major step ahead in InterNet graphics.
