4px padding below every image???

I am very new to WordPress and trying to modify an existing blog template to look like the rest of my site. I am in the process of building the site, so there is no content at the interior pages.

Site address: http://deakynelaw.com/new
Blog Address: http://deakynelaw.com/wordpress/
template css: http://deakynelaw.com/wordpress/style.css
My additional css: http://deakynelaw.com/new/css/styles.css

MY PROBLEM is: at the blog page (http://deakynelaw.com/wordpress/) there is 4px padding (or margin) at the bottom of each page. I tried to modify both of the css files and even put a margin: 0px; padding: 0px; but could not fix it 🙁

If you check my regular home page at http://deakynelaw.com/new, there is NO problem…

PLEASE HELP!!!!
