Increase space between widgets

The problem I have is that the widgets on my wordpress website are all sat too tightly next to each other.

You can see an example of this by clicking this link –>

my .css file is as follows:

/*
	Theme Name: NewsTube
	Theme URI: http://www.theme-junkie.com
	Description: A news/magazine theme designed by <a href="http://j.mp/9bL8oD">Theme Junkie</a>.
	Author: Roy Guan
	Author URI: http://www.theme-junkie.com

	Tags:  2-columns, advertise-ready, widget-ready, advanced-theme-options
