Why not added a div tag?

Found the slider in the Internet, I need to wrap the slider in the header tag with CSS properties: width:100vw; height:100vh; And after slider to make the div with random text. Wrapping the slider, I wrapped. But add a new div does not work, do not understand what the problem is.
