Getting the height from CSS, not from an element in the DOM
<p>I'm creating multiple elements and adding them to the DOM. As I add them the height of the container grows based on the height of the items being added. All the items being added are the same, based off of a CSS class. I would like to set the height of the container DIV before the individual items are added, as they are delayed by an ajax call.</p>

<p>Is there a way to get what the item height will be from the CSS class definition itself rather than having to wait to read it from an element in the DOM?</p>
