title: How to exclude /project/struts/xhtml/styles.css while using <sx:head>
body: <p>In my project when I add <code>&lt;sx:head&gt;&lt;/sx:head&gt;</code> it is including some required javascript and css( /project/struts/xhtml/styles.css ) files to implement Ajax. I don't want css files to be included (I have my own defined css) because it is changing my page format. 
  How to do that?</p>
