IE CSS3 Support WordPress Plugin

CSS3 added usable features, It makes web designing easier. Some of it’s powerful feature are border-radius,box-shadow and border-image. These features are very easy and fun to use on wordpress, specially if you are building themes. Unfotunately , those features won’t work on some IE version with CSS3 alone due to Internet Explorer’s lack of support on those features. Luckily , there is a plugin that makes those CSS3 features dance on Internet Explorer version 6 to 9!

This plugin implement a IE support markup on main style of your theme. This markup is an IE attached behavior which, when applied to an element, allows IE to recognize and display a number of CSS3 properties. It is developed by “Jason Johnston” he called it PIE(Progressive Internet Explorer).

The markup support numbers or CSS3 properties but this plugin can only support spesific properties:

  • border-radius
  • box-shadow
  • linear-gradient



Implement css markup that support CSS3 “border-radius( Rounded box corners )”, “box-shadow( Dropdown/Inner Shadow )” and “linear-gradient( Gradient background )” in IE versions 6 to 9


Upload the IE CSS Support plugin to your site, Activate it then check your site on IE browser. That’s it! :)

Make sure all your “border-radius”, “box-shadow” , and “linear-gradien” are in your theme’s main stylesheet. Your main style usually named “style.css”.
