Move the +1 button a little to the left.|Tweet Like Plusone and Share Plugin|Plugin Support Forum|TECHXT

I see that you have already reduced the margin between the buttons. The gap between the like and the plusone is to cover the width of the like count balloon in case you are getting huge likes. If not then you can reduce the width further by setting the width for the like button by putting the following CSS

.s4fblike{

 width:88px;

}
