[home] reduce spacing between articles

Hi everyone, Thanks for your great theme Catch Box. Here is my website: http://linfotoutcourt.com/ On the Home Page, I would like to: - reduce the spacing between articles (in the "article preview" loop) - reduce the bottom padding inside the article preview, and between the hupso share buttons Here is a screenshot: the red rectangles show the areas I would like to reduce http://i.imgur.com/vl2A7OA.png?1 I've been updating the style.css. Thanks a lot !
