“…make MSIE behave like a standards-compliant browser.”
I’ve come across this little script which can be loaded in a conditional statement in your website’s header, to enable old IE versions (<=7) to display certain CSS properties correctly. This will help you to reduce the amount of CSS you have to rewrite for classic IE browsers: The IE7-js project.
I’m currently testing it on a couple of sites and so far, I didn’t encounter any conflicts with other JS-libs. You can even hot-link the file, but I suggest you copy it to a central place in your environment for the sake of .. well .. organisation. :-) For example, fixing min-/max-/width/height by hand for IE6 becomes obsolete, even tho the script fixes the display only after the whole page has been loaded. This will make it look a little bit “jumpy”. But, heck, my empathy towards IE6 users is shrinking by the day. Check the project website for a complete list of affected properties and CSS-selectors.
