Jquery : How to set the height of a div element dynamically?
jQuery height() method help to set the height of a <div> box dynamically .
The height() method simply returns the element’s height as unit-less pixel value. However calling the height(value) method sets the height of the element, where the value can be either a string (e.g. 100%, 50px, 25em, auto etc.) or a number. If only a number is provided for the value, jQuery assumes it as a pixel unit.
