Getting a dynamically generated elements dimensions

Ive posted this before, but unfortunately I still have yet to resolve
it after numerous attempts...

Here is the overview: populate a container element with some new html
using Element.update and then retrieve the new dimensions of the
containig element.

Here is a bit of code snippet that I would think should work.. but
doesn''t:

==== start snippet ===<style>
.bigBox {
        height: 100px;
        width: 200px;
}

</style>

<script>
var content = ''<span class="bigbox">hello
world</span>'';
$(''debug'').update(content);
var dim = $(''debug'').getDimensions();
$(''debugLog'').update(''height: '' + dim.height
+ '' width: '' +
dim.width);
</script>
</head>
<body>
<span id="debugLog"></span>
<span id="debug"></span>

==== end snippet ===
The results returned are consistently:

mac firefox: height: 14 width: 0
mac safari: height: 17 width: 0

Ive tried setting a timeout by suggestion, which had no effect...
anyone have any ideas?

Re: Getting a dynamically generated elements dimensions

As an update... i added a lil bit of code to check the inner elements
dimensoins using:

$(''debug'').immediateDescendants().each( function(el) {
	var dimE = el.getDimensions();
	$(''debugLog'').update($(''debugLog'').innerHTML
+ ''<br>height: '' +
dimE.height + '' width: '' + dimE.width);
});

and it accurately returns the size of those elements... is it
something do to with css?

Could that
be it?

Re: Getting a dynamically generated elements dimensions

@Colin, ive tried both divs and spans... the numbers do change for the
container... but they are not correct.

@Ken, I noticed some typos in the code i attached as snippets (it was
written on the fly in the window) so I made a pastie with working code
here:
