How to keep post titles while deleting page titles?

Hi I removed the titles on each of my pages by this code: .page .entry-title { display: none; } but then that removed all titles from my posts. Which I want to keep. Can you please help me figure out how to have blogs still use the title automatically from my title, rather than me writing an extra line.
