Column Spacing

I had this question after viewing jQuery Generalization.

I am not sure if you have the final CSS and HTML for reference so I will include them.  The question is how can I increase the column spacings for the drop down?

Final CSS
<style type="text/css">

a , a:hover{
  text-decoration: none!important;
}

.menu-container {
  position: relative;
}
.menu-container .item {
  float: left;
  padding: 0 15px;
}
.menu-container .item > a {
   padding-top: 5px;  
   padding-bottom: 5px;
}
.menu-container:after {
  display: table;
  content: " ";
  clear: both;
}
.sub-menu {
  background: #fff;
  border: 1px solid black;
  display: none;
  position: absolute;
}
.item:hover .sub-menu {
  display: block;
  border-width:1px;
  border-color:green;
  border-radius:20px;
  margin:3px 0 0 0;
}

.item:hover > a {
  background: red;
  color: white;
}
</style>

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You currently have padding:5px; on each column div which adds 5px padding to all four sides of the div. You could increase the right padding for each div by specifying each side independently (top, right, bottom, left).
padding:5px 15px 5px 5px;

Or you could add a right margin to each div.
padding:5px;margin-right:10px;

Open in new window

You may want to omit the right margin for the right-most column.

That's fine.  I went for adding padding:5px 15px 5px 5px; for each column.   Giving the last column less padding might be a bit tricky as I generate the DIVs from a "thick" piece of javascript which reads the data from a JSON structure.
