I've read the other posts regarding this and have tried resetting and adding css. A while ago I changed everything to 9.5px font size. Now I want to change everything to 13px. I have managed this except the post text itself. I can't find the extra bit anywhere. There must be an overriding command somewhere. Can anyone help me find it? Link

posts are styled at ATO->Style POSTS & PAGES this is where you can change the font size
