Bruce on "Bring post title and content closer to top of page"

I'm trying to bring the post title and content closer to the top of the page or closer to the entry-meta. Even though the entry-header has a margin of "0 auto" it seems to have a top and bottom margin or padding, but no matter what I do with the margin in the css below, I can't reduce the top margin.

.singular .entry-header,
.singular .entry-content,
.singular footer.entry-meta,
.singular #comments-title {
margin: 0 auto;
width: 84.9%; /* was 68.9%; */
}

I would include a link to the post, but it's a bunch of garbage at this point and I have it private.

Any ideas?
