I don't modify the intrinsic codes that come along with any application.
I only try to modify the css properties so it comes to a new design.
I see that secondaryContent class is applied in many places which comes with background image as well. This design overlays on the parent container class. this gives me a tough time to modify in some places. Ofcourse i can remove or add new container and css in the template which i am keeping it as last option.
.section .visitorPanel .secondaryContent
