Try decreasing the bottom margin of the paragraphs by adding this to the end of your child theme’s style.css:
p { margin-bottom: 0.5em; }
I’ve tried it and nothing changed. I put it at the extreme bottom of style.css. Is that where you wanted me to put it or at the end of a particular section?
I don’t see the line there when I look at http://www.mgpi.biz/wp-content/themes/Desktop/2011Child.stylecss/style.css
.
Please put the line there and leave it.
Yes, I see it now. And the spacing is reduced. I am guessing that you need to clear the cache for any plugins you are using and for your browser.
