Beispiel 1 jquery mini-modernizr

1. Add a div just after <body> tag.

Direkt nach <body>

 <div class="pl-icon"></div>

2. CSS

.no-js #loader { display: none;  }
.js #loader { display: block; position: absolute; left: 100px; top: 0; }
.pl-icon {
	position: fixed;
	left: 0px;
	top: 0px;
	width: 100%;
	height: 100%;
	z-index: 9999;
	background: url(https://smallenvelop.com/wp-content/uploads/2014/08/Preloader_11.gif) center no-repeat #fff;
}

3. Mini Modernizr

https://wiki.stephanschlegel.de/index.php?title=JavaScript_-_Feature_Detection#Mini_Modernizer_.28JS.2C_Touch.29

4. Loader Script (jQuery)Now add some jQuery to show the pre-loading icon when the page is loading and hide when it has finished loading.

// Wait for window load
$(window).load(function() {
	// Animate loader off screen
	$(".pl-icon").fadeOut("slow");;
});

Beispiel 2

(Gyn Gap 2017) Mit SVG Zirkel, CSS Animation, Stilisiertes Logo und Vorhang rechts links.

HTML - direkt hinter body Tag (Beispiel aus ProcessWire)
