How to place a div on the right side with absolute position

For top right corner try this:

position: absolute;
top: 0;
right: 0;

yourbox {
   position: absolute;
   left: 100%;
   top: 0;
}

left:100%; is the important issue here!

yourbox{
   position:absolute;
   right:<x>px;
   top  :<x>px;
}

positions it in the right corner. Note, that the position is dependent of the first ancestor-element which is not static positioned!

EDIT:

I updated your fiddle.
