Mootools Div overlay

could someone maybe give me a small hint on how to do this with moo开发者_如何学JAVAtools.

Basically i have a div like

<div id="center-panel" style="height: 200px; width 200px; background: green;"></div>

i basically want this div tag hidden by default, and then once the user has been on the website for like two minutes i want the div tag to display>

In an onload handler for your site, use setTimeout() to show the div after 2 minutes:

function showDiv(){
    $('center-panel').setStyle('display', 'block');
};
setTimeout(showDiv, 60 * 1000 * 2);

You can see it in action here with a 2 second delay rather than 2 minutes.
