Hide social widget title?

I’ve created a page with just the social widget on it, using the full-width template, but I don’t want it to show the name of the widget (“social”).
So I’m trying to suppress the entry-id (and entry-header, really).
I have tried this custom css, but it’s not working:

.page-id-148 #entry-title {
   display: none;

Can you suggest how to do this?

My page is http://baysidepc.com.au/social/



entry-title is a class, not an ID. But you’re right, you want the entry-header so do it like this .page-id-148 .entry-header

Thanks. That has totally worked.
