I don't know if it is the best way to achieve it but this is what I did:
Added the following to my "additional.css"
Code:
.bppostbit {
margin-top: 2px;
padding: 3px;
background: url(images/SeamusLight/gradients/back6.png) top left repeat;
border: 1px solid #c4c4c4;
}
If you don't want a background inside the boxes remove the url to the image
Then I used in my postbit legacy for each information I wanted to display in boxes:
Code:
<div class="bppostbit">
code
</div>
