Colorway Theme Menu Text / Icon Padding

Hi
I am hopeful someone can help, I am using the colorway them and added menu icon to the site.
I want to space the icon and the text as they are too close, and also reduce spacing between headers so they fit on one line.
I am not very good with css ( or not really had to do it before) but if someone can let me know the code and where to insert it, it would be very much appreciated.
Here is the site

Hi,

Please paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard

Code:

.menu-item img._mi {
  padding-right: 12px;
}
 
#menu .ddsmoothmenu li{
padding-right: 6px;
font-size: 12px;
}
