W3C CSS Parse Errors

Hi Guys.

I’m using this plugin and it’s great. But, I’m wondering why there are so many CSS parse errors when I do a CSS validation on the W3C website (close to 100) on my website? Most of the CSS parse errors are for the Acronix buttons. Below are some sample errors:

————–
229 .arconix-button-black attempt to find a semi-colon before the property name. add it
229 .arconix-button-black Property progid doesn’t exist : DXImageTransform
229 .arconix-button-black Parse Error DXImageTransform.Microsoft.gradient(startColorstr=’#666666′, endColorstr=’#000000′);
230 .arconix-button-black Parse Error }
235 .arconix-button-black:hover attempt to find a semi-colon before the property name. add it
235 .arconix-button-black:hover Property progid doesn’t exist : DXImageTransform
235 .arconix-button-black:hover Parse Error DXImageTransform.Microsoft.gradient(startColorstr=’#444444′, endColorstr=’#000000′);
236 .arconix-button-black:hover Parse Error }
241 .arconix-button-black:active attempt to find a semi-colon before the property name. add it
