For that, and for tabs, you need to use site CSS (here). I was in the process of prepping a reply for tabs but my specific example also applied to pages as well. Here is an example page that the above CSS applies to. The page content hasn't been filled yet so the tabs all look the same. The first tab is hidden which is why none of them are open when you first land on the page. However, I doubt you will need that so I didn't bother copying that part.

Using your example page. You would want something like this: Your case of selecting a specific single page is a bit simpler that what I have in my example. In my example, I am selecting a bunch of pages whose names have a similar structure.
