Howdy,

On this page: http://alchemisteating.com I would like to change the blog title text "BEETS: THE NEW VIAGRA?" to a smaller font, 18px, without changing the blog title text elsewhere on the site.

I tried this without any luck:
.page-id-17 .entry-title {
font-size: 18px !important;
}

Thanks in advance,
Casper
