Padding at top of pages and posts

Hello. I am trying to alter the padding at the top of a page, but it seems that the same css code controls the top padding on both my pages and posts.

.content {
padding-top: 50px;
}

I only want to change the top padding for my pages (not my posts). Please clarify what CSS needs to be modified to ONLY change the top padding on my pages (without affecting the padding of my posts).

You can see an example of what I want to reduce here: http://snag.gy/nHToW.jpg

Here is the actual live page: http://latitudes.org/parents/free-printable-potty-training-charts-toddlers/

Thanks!
