The main feature of the floating callout is that text can wrap
under and over it because it is a float.
Wraps under and over
You can float a callout to the right using float:right.
You can use width to set the callout's width.
You can use margin to put distance between the callout and
text outside the callout. You can use padding to put space
between the callout's internal text and its borders. You can use
position:relative and top to adjust the vertical
position of the callout.
