Homepage Category Alignment

I'm only selling two products and instead of the two feature boxes appearing only on the left, I'd like them to be either center justified i.e. one center left, the other center right, or, have each one's box be double the width.

Please advise.

 

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.productlisting .pgallery ul.thumbnail li, ul.thumbnail li{
margin: 0 240px 50px 0;
}
.productlisting .pgallery .thumbnail, .thumbnail{
margin-left:74px;
}

 

It's still not looking centered, and for some reason now the Homepage Feature Section isn't responsive. I look forward to your reply, thanks!
