       <p>Note that <code>.height()</code> will always return the content height, regardless of the value of the CSS <code>box-sizing</code> property. As of jQuery 1.8, this may require retrieving the CSS height plus <code>box-sizing</code> property and then subtracting any potential border and padding on each element when the element has <code>box-sizing: border-box</code>. To avoid this penalty, use <code>.css( "height" )</code> rather than <code>.height()</code>.</p>
