More space around the module user1

Hi,
looking at my website ( www.belpassosummerschool.it ) with a smartphone the top menu goes in 2 rows and the second one is really close to the image (as you can see in the screenshot i attached).
How can i increase this distance?

Thanks
Vito Magno

Add this to template_css.css

#topmenu{
margin-bottom:30px;
}
