Im building a draggable map that when the map is dragged the element is given a \'left\' and \'top\' attribute with values for each as so...
Setting the value of a style property to an empty string — e.g. $( "#mydiv" ).css( "color", "" ) — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property.
The docs give you the current, recommended approach for what you're trying to accomplish, which can often save you time because you don't have to read back and forth flame wars on stack overflow (no matter how fun/enlightening that may be!).
