Blog post title not showing up

In my style.css it has:

content .entry-title
font-size:150%;

but in my view source code it says:

content .entry-title
display:none;

That’s the only reason I can see why it wouldnt be displaying the post title. Anyway to fix this problem? My WP blog is only on my localhost atm so I don’t have a link. It’s the Weaver II theme. Thanks for any help!
