Reply To: Hide Page Name

You can get the Page’s ID by going to your Dashboard then go to Pages. Hover your mouse to the specific page then you can see a url at the bottom of your browsers
example:

sample.com/wp-admin/post.php?post=1098&action=edit

The ID here is 1098
Then the code would be:

.post-1098 .entry-title {
    display: none;
}

If you’re not using pretty permalinks then that ID will be visible on the address bar.

It’s a lot easier to get a post or page ID by using firebug for firefox.
