This profile makes minor changes to your site layout and hides the top module zone when you scroll down the page.

Site layout (in Control Panels > Look and Feel > General layout > Site layout) will be set to
Classic Bootstrap (fixed top navbar)

Preference Site logo (feature_sitelogo) will be disabled so that logos and site title are not shown twice

After scrolling down a bit, the fixed top bar will disappear and the topbar zone (if any) will become sticky. This is made through the addition of a module with some javascript.

This profile is best demonstrated after applying the Collaborative Community profile which include site title and topbar module with menus.
