Applying Custom .CSS to only one page

Replies: 0

Hello!

I am not a wordpress developer…but I am trying to learn.

I am trying to apply some custom CSS directly to a single blog page. Everything I read said to do this:

.page-id-4682 h4
{
width: 70%;
margin: 0px 15%;
}

But it doesn’t seem to register it…nothing happens. Any thoughts? I am just trying to move around a single heading to the center of the page. It is like it doesn’t register the whole “.page-id-4682” part, but I’m not sure why.

Thanks!
