Making the size of the pages different and having a scroll down

So, I want to make the pages a little bit bigger in the main page.

In my website it is called “about” and “disclaimer” next to the title “Valuetrends” to the left in the main page. How can I make those pages a bit bigger on the main page? Increase the font I mean.

Also, how can I make a scroll down on these page’s titles? So for example if I create a page called “Real estate” how can that page act as a roll down when you put the arrow over it?

I don’t mean when you click on it. Rather when you put the arrow over it I want it to show different articles on a roll down so you can then click those individual articles.
