         background-image:none}
   .inactiveTab { background-color: lightgrey; color:black;

My controller code goes here  

public class QuickyExtensionController {
  List<Account> quickyList { get; set;} 
    public QuickyExtensionController(ApexPages.StandardController controller) {
              //populate the list on page load 
            quickyList = [Select Quicky__c from Account where Id = : ApexPages.currentPage().getParameters().get('id')];
}

}
