How to format the paragraph, p for all posts?

I have a problem with a gap between the papagraph and the header - if you go to www.careers4u.tv, its between the red bar and the video clip.

I cant find an option for it on the Atahualpa 3.4.9 menu, and css inserts I've tried so far p {...} dont seem to work either...

Any help appreciated.

here is what I would suggest
1) wrap your video clip code in a <div>...</div>
2) add the following CSS to the CSS Inserts

.post-22 div.post-bodycopy p  {display:none !important;}

Its not just one page, its all pages where there's a paragragh... without the paragraph <p> its fine! How do I select the paragragh... is it something like div# something somethingelse p???

ah-ha! This fixes it!

div.post-bodycopy p {display:none !important;}
