Answer 1

This happens when we try to access a resource (CSS...) that is located on a different domain. To deal with this error we can use this:

                   try {
                     //your critical access to ressources !
                     //rules = document.styleSheets[i].cssRules;
                        } catch(e) {
                   if(e.name !== "SecurityError") {
                       throw e;
                       }
