+# Central content
+
+In our ecosystem we have a sidebar and the central content. This content includes the actual content and an [on this page menu](on-this-page) if there is one. The content should be centered in the container that it's place in. We use the `content-wrapper` class to indicate this structure. The [on this page menu](on-this-page) will dissappear at `80em`.

+# On This Page
+
+To allow the users easy and quick access to all the content on the page we provide styling for an `on this page` list, using the `on-this-page-wrapper` class will make sure that the styling of the links is good, and also that it disappears at `80em` to keep the page responsive. This concept should be used within the [central-content](central-content) concept.
