Hiding DIV does not work properly in Opera

Question

My code works great in IE8, Firefox and Safari. But it doesn't work properly in Opera. What happens is that the DIV is hidden but the space occupied by the DIV remains to appear in my web-page.

<div  style=" z-index:-1;height :380; width:760; position:relative; text-align:center" id="new-add">
    <object id="banner-flash" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" 
    codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" 
        width="769" height="382" top="0"> 
    <param name="movie"  value="exp.swf" /> 
    <param name="quality" value="high" /> 
    <param name="bgcolor" value="#ffffff" /> 
    <param name="wmode" value="transparent" />
    <embed src="exp.swf" wmode="transparent" quality="high" bgcolor="#ffffff" width="780" height="382"
 name="mymoviename" align="" type="application/x-shockwave-flash" 
    pluginspage="http://www.macromedia.com/go/getflashplayer"> 
    </embed> 
    </object> 
</div>

<div  id="fechar-link" style=" font-family: Verdana,Arial,Helvetica,sans-serif; font-style: normal; 
    font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-size-adjust: none; 
    font-stretch: normal; text-decoration: none; text-align:center" >
    <a href="#" onclick="
        document.getElementById('new-add').style.height =0;
        document.getElementById('banner-flash').style.height =0;
        document.getElementById('fechar-link').style.height  = 0;

        document.getElementById('new-add').style.visibility ='hidden';
        document.getElementById('banner-flash').style.visibility ='hidden';
        document.getElementById('fechar-link').style.visibility ='hidden';  "  >Close</a>
        </div>

What do I need to do, so the space occupied by the DIV disappears?

Thanks

You might try the style.display property:

Hide

document.getElementById('YourElem').style.display = 'none';

Show

document.getElementById('YourElem').style.display = '';

I don't know if it will solve your problem, but you can try to use :

document.getElementById("xxx").display = "none";

instead of

document.getElementById("xxx").style.visibility = "hidden";
