CSS3 is cool and all web developers would love to use it’s tasty features.  The announced support for CSS3 by such browsers as Opera, Firefox, Safari, Chrome and even IE 9 heats up the interest for this protocol quite a bit, but there’s still an issue of IE 6, 7 and 8.  The fact that IE 9 is not intended to run on XP will probably keep the number of IE 6-8 users high for quite a while.  This is where our discussion of CSS3 could end.  And yet there are efforts to make IE6-8 CSS3 compliant.  Let’s take a look at some of them, many are rather odd.

In a recent article we’ve discussed creating the box-shadow effect viewable in all browsers with the use of filters.  The method has a number of drawbacks of which the biggest is performance.  Here’s another method that’s aimed at efficiency and performance, though it can only be used on blocks with fixed width and height.
