Hi Toddw,

To add the 20px border appears around the entire site go to Appearance -> Customize -> Ambition Theme Options -> Custom CSS and paste the below CSS code then click on Save button.

#page {
    background-color: #2a2a2a;
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
    padding: 20px;
}

Thank you!
