Div-navigator; not have all Divs displayed by default

Div-navigator; not have all Divs displayed by default

So for an articles page on my website, I made a navigation system for users to switch between articles from one month to another. Here is a link to demonstrate:

The complete syntax for this webpage can be found here: http://pastebin.com/pZVTUisy


So as you can see for yourself, the navigation system itself works correctly. However, when you first enter the webpage, instead of displaying no divs, or just the November div, it is displaying all divs. As you can understand, this can result in quite a mess if I were to create a lot of different divs.

So my question to you is, how can I make it so that by default, the webpage will only show the November div, and not the October div?

Help is much appreciated.
