Need css help please

Hi. I am working on a redesign of my site.
This is my current page. http://www.moltenwords.net/
It uses wp-layout.css
I am redesigning using http://www.moltenwords.net/index2.php
It uses wp-layout3.css
I can’t figure out why the h3’s don’t look the same. That would be where it says Behind The Scenes and up in the top right corner where it says Practical Photo…
It’s bolder on the original page and I don’t know why. I have tried looking at all of the codes that seem to apply and they are all the same. I must be missing something…
Can someone please look at this and help me?
Thank you so much.
