What scripts are available for fixing up styling bugs & shortcomings in IE?

Question

There are several helpful JavaScripts and .htc behaviors that patch over the holes & buggy features in Internet Explorer's rendering engine. It seems most of them have some overlapping or incomplete feature support and it's hard to decide what to use:

• DD_Roundies: border-radius
• Fetchak ie-css3: border-radius, box-shadow, text-shadow emulation using VML
• Keith Clark's ie-css3: advanced selector support
• CSS3 PIE: border-radius, box-shadow, border-image, multiple background images, linear-gradient as background image, rgba
• IE PNG Fix: Alpha-transparent PNG support using AlphaImageLoader
• DD Belated PNG Fix: Alpha-transparent PNG support using VML
• Dean Edwards IE[7-9].js: advanced selectors, alpha-transparent PNG, position:fixed, min/max-width/height, box-sizing
• eCSStender: css3 selectors
• Selectivizr: css3 selectors

Which are your preferred scripts? What are the benefits & limitations & gotchas?

Answer 1

Not a script, but probably worth mentioning the Google Chrome Frame plug-in:

Google Chrome Frame is an open source plug-in that seamlessly brings Google Chrome's open web technologies and speedy JavaScript engine to Internet Explorer. With Google Chrome Frame, you can:

• Start using open web technologies - like the HTML5 canvas tag - right away, even technologies that aren't yet supported in Internet Explorer 6, 7, or 8.

• Take advantage of JavaScript performance improvements to make your apps faster and more responsive.
