Hi...A much needed plugin. Thank you!
Here's my shortcode: [spaceboxes id="53767" columns="3" size="spaceboxes-medium-nocrop"]
I'm testing it on this page: http://www.collectorsbluebook.com/collectible-dealer-directory/ (scroll to bottom and you will see the space boxes underneath "Featured Resources".
So here's my question: How do I get this panel of three images to center? They are riding the left margin of the content area and I want to either increase the margin or padding to get them to center under the Featured Resource heading and in the content area. When I add css for padding or margin, it changes all the boxes.
