Page Titles and Entry Header Hidden But Post Titles Not

I have used the following CSS to hide the page titles. I thought I could just unclick enable page titles in the page attributes, but that left a block of space at the top of every page. I don’t want the entry-header on pages, but I would like the post titles on both the posts and on the category pages. How can I accomplish that when using the following CSS doesn’t allow for any titles?

.entry-header {
display: none;
}
