I like the design template. I simply love the aesthetics of the nav menus and the background. The content is also interesting and is targeted at your desired audience.
Here are a few things I would change to improve the experience of the design you have.
I like the zoom menu. I think you may want to consider a few things here. Consider changing the padding-right on list selector to 0.5em. I think this is what's causing your nav links to push over. 1px = 0.06em which is smaller than 0.5em padding you have on the a selector. Use the
Em Calculator when converting px to em. If you decide to keep the zoom effect, you may want to consider making your main content div wider so that it accommodates the second nav bar.
I don't like the scroll inside the scroll on the page because when I scroll to the bottom of the main content, the entire page scrolls. Bringing the google add on the right a bit higher on the page may fix this.
