The theme ships five desktop and three mobile navigations. Which one runs is decided per site – each variant brings its own markup and its own stylesheet, and only the selected one is compiled. That is why every tile below is a page of its own.
Every frame is a real, clickable page at 1280 px wide. Scroll inside a frame to see the header shrink.
The same pages at 390 px wide. Media queries follow the frame width, so this is the real mobile navigation – tap the menu button.
