David,

Css margin short hand code can be a bit confusing at first.

For the quick answer first, the above code means:

Top margin = 0 Right/Left margin = 0 Bottom margin = 10px or pixels

Why?

Here is a little cheat sheet to help you remember:

margin: 20px;  
//All four margins are 20px

margin: 20px 50px;  
//Top & Bottom margin = 20px, left & right = 50

margin: 5px 10px 20px; 
// top=5, left/right=10, bottom=20

margin: 5px 10px 20px 30px;
 // Top=5, Right=10, Bottom=20, Left=30

You are right in that when you specify all four numbers, they are, top, right, bottom, and left respectively.

However, if you only specify three numbers, they are, top, right/left, and bottom. From your example this means: top 0px right and left 0px bottom 10px.
