Size of a changing DIV

[Defacta]

Hello,

I change the content of the div ghp_dpp by this way:

function dis_mess(message) {
var content;
content = "<font style=\"color:#000000;font-style:arial;font-size:
12px;\">&nbsp;" + message + "&nbsp;</font>" ;
layer = document.getElementById('ghp_dpp') ;
layer.innerHTML = content ;
}

So, how can we know the new size of the DIV ghp_dpp ?

Thanks,
Vincent.
