Remove the css styling on HTML

[proxyd]

Hello, I'm developing my webpage and I'm trying to make it as clean as possible (code), I'm using the http://validator.w3.org/ XHTML validator to validate my webpage code, But while using this Featured Content Gallery plugin I get some errors check it here : http://validator.w3.org/check?uri=http%3A%2F%2Fprox.exofire.net%2F&charset=%28detect+automatically%29&doctype=Inline&group=0
Because of some CSS code being generated on the Final Output of my webpage.
Is there anyway I can remove this ? If you want to see it by yoruself check the source code of my we page Line : 68.

Thanks
This is a great plug-in.
