How do i do this..

In your styles Main CSS, add this

/* ***** define box around postbit information ***** */
.info {
padding-left: 3px;
padding-right: 0px;
padding-top: 3px;
padding-bottom: 3px;
background-color: #D1D4E0;
border-top: 1px solid #091524;
border-right: 1px solid #091524;
border-left: 1px solid #091524;
border-bottom: 1px solid #091524;
margin-bottom: 2px;
}

Then around the code you want to "box" use

<div class="info">code goes here</div>
