HTML
<body>
<div id="load"></div>
<div id="contents">
jlkjjlkjlkjlkjlklk
</div>
</body>
JS
document.onreadystatechange = function () {
var state = document.readyState
if (state == 'interactive') {
document.getElementById('contents').style.visibility="hidden";
} else if (state == 'complete') {
setTimeout(function(){
document.getElementById('interactive');
document.getElementById('load').style.visibility="hidden";
document.getElementById('contents').style.visibility="visible";
},1000);
}
}
CSS
#load{
width:100%;
height:100%;
position:fixed;
z-index:9999;
background:url("https://www.creditmutuel.fr/cmne/fr/banques/webservices/nswr/images/loading.gif") no-repeat center center rgba(0,0,0,0.25)
}
Note:
you wont see any loading gif if your page is loaded fast, so use this code on a page with high loading time, and i also recommend to put your js on the bottom of the page.
