Selector to apply margin between search results items?

I would like to add/increase margin-top of the items shown on the search results page. I already added this for blog posts, which also works perfectly for blog posts that appear in the search results:

#content .post {
	margin-top: 50px;
}

#content .post:first-child {
	margin-top: 0;
}

However, every other item in search results doesn’t have any margin-top. What selector do I need to use to target pages, not only posts?

Thank you! ??
