How to remove lines between your sidebar items

Go to your layout page and click 'edit html' .  Hit 'Ctrl f' and a find box will pop up at the bottom of your screen.  Paste this code in the box .sidebar .widget  It should take you to this part of your code:

.sidebar .widget, .main .widget {
  border-bottom:1px dotted $bordercolor;
  margin:0 0 1.5em;
  padding:0 0 1.5em;
 }


Change the 1px to 0px.  Preview it to make sure you like the new look, then save it!
