I recently came across an intriguing script while trying to find a fix for a CSS bug. It’s called IE7.js, and it claims “to make Microsoft Internet Explorer behave like a standards-compliant browser,” and to fix PNG transparency in IE5 and IE6 to boot.
Are you just a couple of scripts away from never again having to find a workaround for an IE CSS bug? Probably not. I haven’t had the time to test the script extensively, but the test pages look promising. It will make things a lot easier for you, but I doubt it will magically make everything work flawlessly in IE.
