Home Page Slider

Hello, I want to use a home page slider plugin and it seems to be working fine. However, there is a large margin or white space between the top of the slider and the header secondary menu on the home page. I do not want any space, the top of the slider should be flush up against the menu. Also, under the menu there should be a larger margin between the H1 title of the page and the slider. Can you send the CSS code for this? Thanks! My website is iglobal.net
