News link opening at an other div

I’m referring to this site: Click
First you have to click at the right on: show info, to see the site. I have to fix this too.

My question is a little bit more complicated I think.
I have installed a widget called ‘latest news’ in the ‘footer sidebar’. This widget shows the links of the latest 5 newstitles.
Normally when I click on one of those links, a ‘standard’ page opens with only the text.
Actually I want that this link opens in a fullscreen background mode. On the place where I put the other texts (so in that bar at the right which can be opened or closed)

So, you see at the left a white block. The left side of the block is the menu div.
The right side of that block is the ‘show info/hide info’ block (normally at the right side of the page).
In the bottom of the right side you see 5 newslinks (beneath the header: LAATSTE NIEUWS)
That’s the sidebar: ‘footer’
So, actually when I click on a newslink, I want the news appear instead of the ‘home’ text you see at the screenshot.

I hope you guys have an answer.
