Absolute

In this layout, #div_2 has the positioning property of absolute and placement values applied to the top and right sides. Absolute positiong places the <div> in relation to the edges of the page. By doing this, #div_2 is now independent of the original layout. Note that #div_3 has moved up to take the space formerly occupied by #div_2
