eliminate margin above and below header

Hey guys! I've finally got my slider working properly and it is 100% width, but I have a margin of white above and below it which needs to be gone. I added this to my css includes but it didn't fix it. Site: http://www.woosa.it Theme: Suffusion

header#header {
display: none;
}
div#header-widgets {
width: 100%;
}
div#wrapper {
padding: 0;
margin: 0;
max-width: 100%;
}

#header-container div#text-8 {
margin: 0;
}
