Gather Theme page title size

Hi,
I purchased “Gather” theme recently and I’m building my graphic design site.

Visually it works fine for me, except for one thing: the page titles (what it calls the “Secondary font”) are VERY big and have too much space above and below. And the side margins are wide as well. So, lots of wasted white space on my pages.

I’ve tried to edit the title font size, padding, margins, in the CSS code, but it displays the same.

If I eliminate titles, and instead use headers inside the text tables, that of course causes problems organizing the pages.

PLEASE tell me how to change the code, to make the title font only twice the size of the text, not 4 times the size.

Right now it’s still on private cause it’s not finished, but the URL will be http://digital-genie.com .

Thank you!! ~ Dina
