Cascading Style Sheets and HTML Style
Almost all HTML tags can have style attributes that can be changed.
Often used to allow a <div> so that other content wraps around it . Placing many floated elements next to each other means web browser will dynamically jiggle them around to fit the width of the window.
This directive tells web browser to reset floated elements from this point forward.
On its own this directive doesn't appear to do anything useful.
However, placing a absolute <div> inside a relative <div> is handy way to align elements to the sides or top of the relative <div> container.
