Hi everyone, I am just learning about coding, and would like to ask you few questions. This website was using forte template and modified it http://www.aifny.com/ Is there any possibility to increase the space from the top of the page and title/navigation bar? Also still trying to find a code to remove background for the arrows but few codes that I used doesn't work... And the last question is how to dim slightly entire page when you drag mouse on the navigation bar? Any help is appreciated.
