Seperator in "Latest news module"

Like in this topic, I am facing the same issue.

I have tried the code in the other topic

body #eb.mod_easyblogmostpopularpost .mod-grid-1 + .mod-grid-1 .mod-item {

	border-top: 1px solid #d7d7d7;

	padding-top: 15px;

}

And I have replaced

easyblogmostpopularpost

with

easybloglatestblogs

but I can't get it to work.

Am I missing something?
