Usually the last element jumps to the bottom due to space constraints, my suggestion is to try giving each DIV inside the Div.Basket a border and check each div width, most probably you’ll notice that the last element doesn’t have enough space to fit inside the box, if this is the case then just reduce the width of any of the div’s to make space.
