i've been trying to solve this issue but having too much difficulty i'm turning to you guys.

if you go to the link above you'll see the spacing between the paragraphs is one amount, and then say go to the actual article page and you'll notice the spacing increases between paragraphs.

anyone know why this is happening? cannot find where the difference is coming from.
