Cascading Style Sheet Compatibility in Internet Explorer 7
Now that IE 7 is close to be released to the wilderness of our world, it's time to consider CSS compatibilities.
Well bad news folks! I think we will have to consider another series of bloated CSS to overcome the differences between IE 7 and before IE 6.
I rely a lot on the * html trick in some recent projects and it seems that now in IE 7 this won't work anymore. Hold on my clients will still use IE 6 for a long time. It means I will have to create more tests, welcome to the crazy world of web developers ;-)
Check this document (preliminary one anyway) by Microsoft on the issues you should expect with CSS. Some call this good news because IE is finally (not completlely) compliant with CSS 2 but I call that overwork time like if I have nothing else to do.
