In some cases you may want to adjust the border margins or "padding" between widgets and sections on your page. Here's how to adjust the margins:
1. Click Site Settings in the top right of the screen.
2. Click Border Margins, underneath the heading Look and Feel.
3. Set the desired padding between Section Margins and Widget Margins (the default padding for Section Margins is 40 pixels, and for Widget Margins 20 pixels).
4. Click Save.
