I want to hide the body of my web page. Once the all content of the body tag of the web page are ready to display I want to show it body, but until that time I want to show some loading image.
If for some reason the content of the body does not load properly I want to show an error message.
What is the best way of doing this in javascript?
It's pretty simple actually. You'll have to position a full screen div
over your page and hide it once the onload
function is triggered.

}
</style>

<body>
<div id="loading-overlay">This is a loading screen</div>
<p>The page has loaded!</p>
