Today we want to show you how to create a very simple page preloading effect with CSS animations, SVG and JavaScript. For websites, where it’s crucial to load all or part of the assets, these kind of preloader screens can be a creative way to make waiting a bit less boring for the visitor. The idea for this tutorial is based on the beautiful preloading effect seen on the website of Fontface Ninja. Initially, the logo and a circular progress element slide up and when the loader finishes its progress animation, i.e. the page assets are loaded, the whole “header” moves up while the page elements are revealed with yet another animation. The sliding logo with its color change makes the icing on the cake.
In this tutorial we will re-create the effect seen on Fontface Ninja with some adjustments and a second demo with slightly different effects. For the logo and the circular progress element we will use inline SVGs, so that we can style their paths in our CSS. We’ll create a little script for the stroke animation of the SVG loading element and then we’ll control the page animations with classes that we add to the main container.
Please note that we’ll be using CSS animations and CSS 3D transforms, so this will only work as intended in browsers that support them.
So, let’s get started!
The Markup
Let’s wrap a header and the main content division into a container. We have to keep in mind that we want to control anything that happens to the initial view and the content with classes. So we will use the main container as our control element. We give it the class and ID ip-container.
The initial view consists of a header that contains the logo and the loading element. They are both SVGs and our logo is a bit more complex than the loader, so we’ll leave out the path coordinates in the snippet below because its really long. As you can see, we are defining some SVG attributes like the width and height, the viewBox
and the preserveAspectRatio
. The value for the preserveAspectRatio
is xMidYMin meet which means that we force uniform scaling where the graphic fits completely into its container while its centered on the X axis and aligned at the top. In order to make the logo accessible, we add a title, description and the necessary ARIA attribute, aria-labelledby.
The main content has the class ip-main and later on we’ll apply animations to its children, the headline, the division and the inner boxes:
<div id="ip-container" class="ip-container"> <!-- initial header --> <header class="ip-header"> <h1 class="ip-logo"> <svg class="ip-inner" width="100%" height="100%" viewBox="0 0 300 160" preserveAspectRatio="xMidYMin meet" aria-labelledby="logo_title"> <title id="logo_title">Delightful Demonstrations by Codrops</title> <path d="...our super-long path..." /> </svg> </h1> <div class="ip-loader"> <svg class="ip-inner" width="60px" height="60px" viewBox="0 0 80 80"> <path class="ip-loader-circlebg" d="M40,10C57.351,10,71,23.649,71,40.5S57.351,71,40.5,71 S10,57.351,10,40.5S23.649,10,40.5,10z"/> <path id="ip-loader-circle" class="ip-loader-circle" d="M40,10C57.351,10,71,23.649,71,40.5S57.351,71,40.5,71 S10,57.351,10,40.5S23.649,10,40.5,10z"/> </svg> </div> </header> <!-- main content --> <div class="ip-main"> <h2>Make yourself at home.</h2> <div class="browser clearfix"> <div class="box"> <span class="icon-bell"></span> <p>...</p> </div> <div class="box"> <span class="icon-heart"></span> <p>...</p> </div> <div class="box"> <span class="icon-cog"></span> <p>...</p> </div> </div> </div> </div><!-- /container -->
Let’s go on and style this.

The CSS
Note that the CSS will not contain any vendor prefixes, but you will find them in the files.
Initially, we’ll include some fonts that we’ll need for the dummy text and the icons in the boxes. The icons used in the demos are from the Feather icon set and we’ve created the icon font with the Icomoon App. The dummy font is Blokk, a really great fonts when creating wireframes and mockups.
@font-face { font-weight: normal; font-style: normal; font-family: 'Blokk'; src: url('../fonts/blokk/BLOKKRegular.eot'); src: url('../fonts/blokk/BLOKKRegular.eot?#iefix') format('embedded-opentype'), url('../fonts/blokk/BLOKKRegular.woff') format('woff'), url('../fonts/blokk/BLOKKRegular.svg#BLOKKRegular') format('svg'); } @font-face { font-weight: normal; font-style: normal; font-family: 'feather'; src:url('../fonts/feather/feather.eot?-9jv4cc'); src:url('../fonts/feather/feather.eot?#iefix-9jv4cc') format('embedded-opentype'), url('../fonts/feather/feather.woff?-9jv4cc') format('woff'), url('../fonts/feather/feather.ttf?-9jv4cc') format('truetype'), url('../fonts/feather/feather.svg?-9jv4cc#feather') format('svg'); }
We want the header to fill all the viewport initially, so let’s give it a 100% in width and height and set its position to fixed
:
.ip-header { position: fixed; top: 0; z-index: 100; min-height: 480px; width: 100%; height: 100%; background: #f1f1f1; }
Let’s remove any margins from the logo headline:
.ip-header h1 { margin: 0; }
Both, the logo and the loader will be positioned absolutely and we’ll stretch them over the viewport:
.ip-logo, .ip-loader { position: absolute; left: 0; width: 100%; opacity: 0; cursor: default; pointer-events: none; }
Instead of simply taking the logo element and positioning it in the center of the header, we need to keep the following in mind: we want the logo SVG itself to be responsive, meaning that we might not have knowledge about its dimension, and we want to move it to the top of the main content using 3D transforms, once the loading is done. Mainly, because we don’t know the size of our logo, we don’t know how much we have to actually translate it in order to be at the top of the content (percentage translations take the element as reference and not the parent). But we do know and can work with one particular value: the viewport height. So let’s just set the logo to 100% height and translate it 25% so that the logo SVG stays in the middle of the page:
.ip-logo { top: 0; height: 100%; transform: translate3d(0,25%,0); }
We position the logo element at the bottom of the viewport:
.ip-loader { bottom: 20%; }
The SVGs, which we gave the class ip-inner, will be displayed as block element and we center it horizontally with the auto margin:
.ip-header .ip-inner { display: block; margin: 0 auto; }
The logo SVG should be responsive but not become too big or too small. So, beside a percentage value as the width, we also set a max and min width:
.ip-header .ip-logo svg { min-width: 320px; max-width: 480px; width: 25%; }
Since we’ve added the logo SVG inline, we can directly style the color of the path:
.ip-header .ip-logo svg path { fill: #ef6e7e; }
And the same holds for the loader:
.ip-header .ip-loader svg path { fill: none; stroke-width: 6; }
The first path has a gray fill:
.ip-header .ip-loader svg path.ip-loader-circlebg { stroke: #ddd; }
And the second path will have the progress transition that we will control in our JS. But here, we’ll define the transition of the stroke-dashoffset
:
.ip-header .ip-loader svg path.ip-loader-circle { transition: stroke-dashoffset 0.2s; stroke: #ef6e7e; }
And now, we’l style the content of the page, which is all wrapped in the ip-main division:
.ip-main { overflow: hidden; margin: 0 auto; padding: 160px 0 10em 0; max-width: 1100px; width: 90%; }
The headline will be sized with vw
which will make it responsive:
.ip-main h2 { margin: 0; padding: 0.5em 0 1em; color: #be4856; text-align: center; font-size: 4.25em; font-size: 4vw; line-height: 1; }
Let’s add a browser image:
.browser { margin: 0 auto; padding-top: 8%; min-height: 400px; max-width: 1000px; width: 100%; border-radius: 8px; background: #fff url(../img/browser.png) no-repeat 50% 0; background-size: 100%; color: #d3d3d3; }
And some dummy boxes:
.box { float: left; padding: 3.5em; width: 33.3%; font-size: 0.7em; line-height: 1.5; } .box p { font-family: 'Blokk', Arial, sans-serif; }
The boxes will each have an icon:
[class^="icon-"]::before, [class*=" icon-"]::before { display: block; margin-bottom: 0.5em; padding: 0.5em; border-radius: 5px; background: #dfdfdf; color: #fff; text-align: center; text-transform: none; font-weight: normal; font-style: normal; font-variant: normal; font-size: 5em; font-family: 'feather'; line-height: 1; speak: none; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; } .icon-bell:before { content: "e006"; } .icon-cog:before { content: "e023"; } .icon-heart:before { content: "e024"; }
Now we have to define the animations that should take place. As we mentioned earlier, we will control the firing of animations by adding classes to the main container.
The initial animation of the header elements will make them move in from the bottom:
.loading .ip-logo, .loading .ip-loader { opacity: 1; animation: animInitialHeader 1s cubic-bezier(0.7,0,0.3,1) both; } .loading .ip-loader { animation-delay: 0.2s; } @keyframes animInitialHeader { from { opacity: 0; transform: translate3d(0,800px,0); } }
We only need to define the from keyframe since we want to move the elements to their original position.
The custom cubic-bezier timing function, will add a nice smoothness to the effect. The loading element needs to have a slight delay before it slides in.
At this point, let’s keep in mind, that we will animate the circular progress with JS. So we need another “state” which will be switched to, once that progress animation is done. We will give the class loaded to the container and apply the following animations:
.loaded .ip-logo, .loaded .ip-loader { opacity: 1; } .loaded .ip-logo { transform-origin: 50% 0; animation: animLoadedLogo 1s cubic-bezier(0.7,0,0.3,1) forwards; } @keyframes animLoadedLogo { to { transform: translate3d(0,100%,0) translate3d(0,50px,0) scale3d(0.65,0.65,1); } } .loaded .ip-logo svg path { transition: all 0.5s ease 0.3s; fill: #fff; } .loaded .ip-loader { animation: animLoadedLoader 0.5s cubic-bezier(0.7,0,0.3,1) forwards; } @keyframes animLoadedLoader { to { opacity: 0; transform: translate3d(0,-100%,0) scale3d(0.3,0.3,1); } }
The logo moves down 100% (remember, our logo is 100% of the viewport height, so this will make it move the entire screen height) plus a bit more for some spacing, and then we also scale it down a bit. The color of the SVG path will change with a transition.
The loader element moves up, scales down and fades out.
The fixed header itself needs to move up as well:
.loaded .ip-header { animation: animLoadedHeader 1s cubic-bezier(0.7,0,0.3,1) forwards; } @keyframes animLoadedHeader { to { transform: translate3d(0,-100%,0); } }
Let’s take care of the content elements. Here, you can do a lot of creative effects. This of course, all depends on what content you have on the page. In our case, we want to fade the elements in while moving them up from below:
/* Content animations */ .loaded .ip-main h2, .loaded .ip-main .browser, .loaded .ip-main .browser .box, .loaded .codrops-demos { animation: animLoadedContent 1s cubic-bezier(0.7,0,0.3,1) both; } .loaded .ip-main .browser, .loaded .ip-main .browser .box:first-child { animation-delay: 0.1s; } .loaded .ip-main .browser .box:nth-child(2) { animation-delay: 0.15s; } .loaded .ip-main .browser .box:nth-child(3) { animation-delay: 0.2s; } @keyframes animLoadedContent { from { opacity: 0; transform: translate3d(0,200px,0); } }
The slight delay for the boxes in the browser division, will create a nifty extra effect.
In order to avoid problems with scrolling and gaps at the bottom of the page, we need to switch the positioning of the header from fixed to absolute. This, we can control by adding a class to the body (or any parent) once all the animations are done. With the help of that class, we switch the positioning:
.layout-switch .ip-header { position: absolute; }
If we don’t have JavaScript, we show the state after all animations. This we can do by setting the header to relative positioning and sizing the logo accordingly:
.no-js .ip-header { position: relative; min-height: 0px; } .no-js .ip-header .ip-logo { margin-top: 20px; height: 180px; opacity: 1; transform: none; } .no-js .ip-header .ip-logo svg path { fill: #fff; }
Last, but not least, we have to take care of the large headline and the boxes for smaller screens:
@media screen and (max-width: 45em) { .ip-main h2 { font-size: 2.25em; font-size: 10vw; } .box { width: 100%%; } }
And that’s all the style.
The JavaScript
The JavaScript consists of two parts. We will separate the general progress element’s loading functionality from the rest. Let’s call that script pathLoader.js since it is the path element that animates.
We want to be able to set the stroke-dashoffset in order to animate the filling the path. Initially, this and the stroke-dasharray are set to the length of the path (getTotalLength()). We draw the path by setting the dash offset to a lower value up until zero where the path is totally drawn. This is done by calling the setProgress function with a parameter for the value. The optional callback parameter might be useful if we want to execute some code once the value is set and the transition is finished.
function PathLoader( el ) { this.el = el; // clear stroke this.el.style.strokeDasharray = this.el.style.strokeDashoffset = this.el.getTotalLength(); } PathLoader.prototype._draw = function( val ) { this.el.style.strokeDashoffset = this.el.getTotalLength() * ( 1 - val ); } PathLoader.prototype.setProgress = function( val, callback ) { this._draw(val); if( callback && typeof callback === 'function' ) { // give it a time (ideally the same like the transition time) so that the last progress increment animation is still visible. setTimeout( callback, 200 ); } } PathLoader.prototype.setProgressFn = function( fn ) { if( typeof fn === 'function' ) { fn( this ); } }
The setProgressFn method is used here to define a possible way to interact with the loader. For instance, for our demo we are not preloading anything but instead we simulate a loading animation by setting a random value between 0 and 1 throughout a set of time intervals:
var simulationFn = function(instance) { var progress = 0, interval = setInterval( function() { progress = Math.min( progress + Math.random() * 0.1, 1 ); instance.setProgress( progress ); // reached the end if( progress === 1 ) { clearInterval( interval ); } }, 100 ); }; var loader = new PathLoader([pathselector]); loader.setProgressFn(simulationFn);
Next, let’s create our resting script in main.js. First we initialize and cache some variables:
var support = { animations : Modernizr.cssanimations }, container = document.getElementById( 'ip-container' ), header = container.querySelector( 'header.ip-header' ), loader = new PathLoader( document.getElementById( 'ip-loader-circle' ) ), animEndEventNames = { 'WebkitAnimation' : 'webkitAnimationEnd', 'OAnimation' : 'oAnimationEnd', 'msAnimation' : 'MSAnimationEnd', 'animation' : 'animationend' }, // animation end event name animEndEventName = animEndEventNames[ Modernizr.prefixed( 'animation' ) ];
We start the initial animation (both logo and loader slide up) by adding the loading class to the main container. After the animation ends we start the “fake” loading animation on the SVG loader element like explained before. Note that while these animations are taking place we don’t allow the page to be scrolled.
function init() { var onEndInitialAnimation = function() { if( support.animations ) { this.removeEventListener( animEndEventName, onEndInitialAnimation ); } startLoading(); }; // disable scrolling window.addEventListener( 'scroll', noscroll ); // initial animation classie.add( container, 'loading' ); if( support.animations ) { container.addEventListener( animEndEventName, onEndInitialAnimation ); } else { onEndInitialAnimation(); } } // no scroll function noscroll() { window.scrollTo( 0, 0 ); }
Again, we will simulate that something is being loaded by passing a custom function to the setProgressFn. Once the animation is finished we replace the loading class with the loaded class which will initiate the main animations for the header and the content. After that’s done, we add the layout-switch class to the body and allow scrolling:
function startLoading() { // simulate loading something.. var simulationFn = function(instance) { var progress = 0, interval = setInterval( function() { progress = Math.min( progress + Math.random() * 0.1, 1 ); instance.setProgress( progress ); // reached the end if( progress === 1 ) { classie.remove( container, 'loading' ); classie.add( container, 'loaded' ); clearInterval( interval ); var onEndHeaderAnimation = function(ev) { if( support.animations ) { if( ev.target !== header ) return; this.removeEventListener( animEndEventName, onEndHeaderAnimation ); } classie.add( document.body, 'layout-switch' ); window.removeEventListener( 'scroll', noscroll ); }; if( support.animations ) { header.addEventListener( animEndEventName, onEndHeaderAnimation ); } else { onEndHeaderAnimation(); } } }, 80 ); }; loader.setProgressFn( simulationFn ); }
And that’s it, all done!
We hope you enjoyed this tutorial and find it useful and inspiring!

Demo seems to be broken?
Hi Toine,
which browser/OS are you using and what are you seeing?
Thanks for the feedback,
cheers, ML
Thanks for using our browser freebie!
You can download it here: http://keyners.pl/freebie/simple-browser-psd
Demo seems to be broken on android =/
Working perfectly fine on my Android – HTC One M8!
on my android 2.3 too … with standard browser nothing seen, dolphin messy & only partially depicted, no logo; opera mini same. pity
Beautiful and functional as always Manoela. Thanks for sharing.
Could not run the demo on IE8 (Windows 7) It only show blank page 🙁 I think we should give them some chance – at least to view page content.
IE8? Really? I wonder how this demo works on an abacus? Has anyone tried that?
well… this articles is IE10+
If you developt for IE8 it isn’t your fav site 😉
Nice one SR.
IE… LOL. is that still a thing?
nicely done !!!!
(if i may, you missed the logo transitioning mask we made on fontface.ninja 😉 )
For the life of me, I cannot get my SVG logo to appear here. Possible to use another format instead?
Pretty cool!
ML, This is great. Thanks for the demo.
Like your new pic Mary 😉 and ….. tanx for really nice stuff 🙂
How to make on my own logo? Is there any SVG path generator?
it’s easy with
http://vectormagic.com/
You’re one of the last bloggers worth reading.
Keep bringing us gold content.
Cheer.
excellent I will use in same project, nice work!
Thanks for the included JS.
Freaking slick! I remember when preloaders were totally shunned, but now people are dying for good ones! This is why I love Web-Design 🙂
I’m not sure how to use SVG path O.o
Great tutorial, I’ve bookmarked this and plan to mess around with it on my next project. I really like page preloaders and wish they were used more often.
Thanks for this Mary. How would I implement this if I wanted to use it with a slider? For example, on my site right now a slider loads but often it loads a lot slower than eeverything else on the page, I’d love for some sort of loading effect to at least show in it’s place while it loads, any ideas?
Hi, I’m a learning developer working essentially with WordPress. Would it be possible to implement this loader with dynamic material? Willing to try but doesn’t want to mess for hours before finding it impossible 😉 Thx in advance!
Thanks for the article.
Do you have any thoughts on how to have the preloader actually load live data from the page, ie images so that the progress bar / circle is a real representation as opposed to simply a nice effect?
Thanks,
Rooster
Hi!
I wonder if I were to use this to actually preload all the assets on the site (mainly images) how I would do that? My guess is that you have to change the simulationFn function and then pass it to setProgressFn on the loader element.
My idea is to implement this image gallery: http://tympanus.net/codrops/2014/03/21/google-grid-gallery/ alongside with some more content on the site.
Tips are highly appreciated! Thanks for your excellent work. It is really inspiring! 😀
I second this. I’m struggling to find a resource that discusses pre-loading content and how to coordinate this with a progress bar.
Same here, I’m not sure how to actually link actual resources to the loading animation. How do you determine if the resource is loaded or how long will it take?
Apart from that, the example rocks. Thank you Mary.
Victor – yes you can do this. You would just need to use Desandro’s imagesloaded.js and tie the progress method to the total image count in the timer.
https://github.com/desandro/imagesloaded
Hi Ian A, tanks a lot for your answer !
Do you have a link or a tutorial that explains how to use Desandro’s method please ?
My development skills are really low so i’m a little lost 😉
Hi Ian,
I was having a look and right now I tried something like this:
var imgLoaded = $(‘body’).imagesLoaded().progress( function( instance, image ) {
var result = image.isLoaded ? ‘loaded’ : ‘broken’;
console.log( ‘image is ‘ + result + ‘ for ‘ + image.img.src );
});
and then on the “simulationFn” I am passing “imgLoaded” as the progress variable and later on checking if progress. The animation works, but I can’t see the loading actually happening. It goes straight from the initial animation to the other. Here it is how it looks like:
function startLoading() {
var imgLoaded = $(‘body’).imagesLoaded().progress( function( instance, image ) {
var result = image.isLoaded ? ‘loaded’ : ‘broken’;
console.log( ‘image is ‘ + result + ‘ for ‘ + image.img.src );
});
var simulationFn = function(instance) {
var progress = imgLoaded,
interval = setInterval( function() {
progress = imgLoaded;
instance.setProgress( progress );
// reached the end
if( progress ) {
classie.remove( container, ‘loading’ );
classie.add( container, ‘loaded’ );
clearInterval( interval );
var onEndHeaderAnimation = function(ev) {
if( support.animations ) {
if( ev.target !== header ) return;
this.removeEventListener( animEndEventName, onEndHeaderAnimation );
}
classie.add( document.body, ‘layout-switch’ );
window.removeEventListener( ‘scroll’, noscroll );
};
if( support.animations ) {
header.addEventListener( animEndEventName, onEndHeaderAnimation );
}
else {
onEndHeaderAnimation();
}
}
}, 80 );
};
loader.setProgressFn( simulationFn );
}
Here you go guys, on main.js:
(function() {
var support = { animations : Modernizr.cssanimations },
container = document.getElementById( ‘container’ ),
header = container.querySelector( ‘header.header’ ),
loader = new PathLoader( document.getElementById( ‘loader-circle’ ) ),
animEndEventNames = { ‘WebkitAnimation’ : ‘webkitAnimationEnd’, ‘OAnimation’ : ‘oAnimationEnd’, ‘msAnimation’ : ‘MSAnimationEnd’, ‘animation’ : ‘animationend’ },
// animation end event name
animEndEventName = animEndEventNames[ Modernizr.prefixed( ‘animation’ ) ],
imgCount = $(‘#container img’).length,
imgLoaded = 0;
function init() {
var onEndInitialAnimation = function() {
if( support.animations ) {
this.removeEventListener( animEndEventName, onEndInitialAnimation );
}
startLoading();
};
// disable scrolling
window.addEventListener( ‘scroll’, noscroll );
// initial animation
classie.add( container, ‘loading’ );
if( support.animations ) {
container.addEventListener( animEndEventName, onEndInitialAnimation );
}
else {
onEndInitialAnimation();
}
}
function startLoading() {
$(‘#container’).imagesLoaded()
.progress( onProgress )
.done( onComplete );
}
function onProgress() {
imgLoaded++;
loader.setProgress(imgLoaded/imgCount);
}
function onComplete() {
classie.remove( container, ‘loading’ );
classie.add( container, ‘loaded’ );
var onEndHeaderAnimation = function(ev) {
if( support.animations ) {
if( ev.target !== header ) return;
this.removeEventListener( animEndEventName, onEndHeaderAnimation );
}
classie.add( document.body, ‘layout-switch’ );
window.removeEventListener( ‘scroll’, noscroll );
};
if( support.animations ) {
header.addEventListener( animEndEventName, onEndHeaderAnimation );
}
else {
onEndHeaderAnimation();
}
}
function noscroll() {
window.scrollTo( 0, 0 );
}
init();
})();
Wow! its nice.
Great! Thanks!
Hy Mary Lou, congratulation ! this is very cool !!
I’ve tried to include this loader on my website but it only works when i reload my page, i think i have some problems with my js but i really don’t know how to fix it.
Please, do anyone have an idea about it ?
Thanks a lot !
Wow really nice job can’t wait to use it for my own website !
Could somebody explain me how to delete the simulated content to load the ip-container content for real ?
Thanks in advance !
Thank you for the tutorial , I currently have many errors issues I’m fixing. Thanks for the tips!
Awesome! Thanks a lot!
Can you help me to improve this script for do real preload images? Anyway thanks a lot for this script!!! Is amazing!
As I mentioned in another comment above, Google a JS called “imagesloaded” by desandro
very good tutorial! thank you.
Well done!
Good job 🙂
Hello,
thanks for the good tutorial.
I have some questions:
– what the [class^=”icon-“]::before and [class*=”icon-“] mean? Why not [class=”icon”-]::before?
Thank you so much!
Hi, guys! I tried to use this good trick in my project (builded on wordpress), I put my svg in your project and all works fine, but I cant put your project into my wordpress theme. Did anyone tried this? I actually need help, cause this trick is very cool, but I want it to use in dynamic page.
That’s great – Thank you
Is there a way to keep the main logo from scaling down when loaded?
great tutorial
I’m working on our next generation website, and have implemented the page preloading effect (works good) but when the preloader comes up, there are two elements from the loaded page that appear on the preloader. These elements belong to a bxslider feature and a megamenu.
I’ve attempted to hide these elements by setting their style as follows:
.loading .megamenu_container .loading .bx-controls-direction { display: none; }
but this does not hide the two elements that are on the page. The elements that are displayed are the list/menu from the megamenu and the direction controls for the bxslider. I’m wondering if anyone else has encountered a similar problem and how they were able to fix it.
thanks in advance for your help!
enthusiastically, Mark H
Hi, I used it and it looks amazing, but I have only one question, Do you know how to set the cookies so it works only the first time? I try with a lot of codes but I delete the div and the site get stuck and everything stop working,
Can somebody help me? I will really appreciate!
Thanks..
Hi,
What is the best method to convert a png/jpeg image to svg line drawings? It must take a very long time to write the svg line drawing for the ‘Delightful demonstrations’ logo used in the demo?
its simply amazing and i am trying to apply your technique in my newly under development wordpress coming soon page, you did fabulous job.
Hey, I if you could help me to apply this effect in my wordpress project, it would be great help.
Hello, it has an issue
Whenever the page loaded it doesn’t keep the scroll position, it shows page from top!!.. It brings a problem in onepage site…
for eg. http://localhost/#midofpage if i type this address and hit enter means it won’t go to the #midofpage section.. it stays at top..
Anyone have the solution!!.. kindly help me..
In main.js file, there is a function call to noscroll
And the function sets the scroll to top of the page,
function noscroll() {
window.scrollTo( 0, 0 );
}
You have to remove this.
For those wondering how to link the loading effect to the progress of the page loading, here’s a solution I’ve implemented :
For that, I’ll be using Pace.js (http://github.hubspot.com/pace/docs/welcome/)
Just add this script to your page, then in your main.js file modify the startLoading() function this way :
function startLoading() {
// simulate loading something..
var simulationFn = function(instance) {
var progress = 0;
var myTimer = setInterval(function() {
var temp = $(‘.pace-progress’).attr(‘data-progress-text’);
progress = parseFloat(temp) / 100.00;
instance.setProgress(progress);
if (progress == 1) {
clearInterval(myTimer);
console.log(‘Page fully loaded’);
if (progress >= 1) {
classie.remove(container, ‘loading’);
$(‘button.trigger’).removeClass(‘gone’);
classie.add(container, ‘loaded’);
progress = null;
var onEndHeaderAnimation = function(ev) {
if (support.animations) {
if (ev.target !== header) return;
this.removeEventListener(animEndEventName, onEndHeaderAnimation);
}
classie.add(document.body, ‘layout-switch’);
window.removeEventListener(‘scroll’, noscroll);
$(‘.title’).velocity({
opacity: 1,
}, {
duration: 500
});
};
if (support.animations) {
header.addEventListener(animEndEventName, onEndHeaderAnimation);
} else {
onEndHeaderAnimation();
}
}
}
}, 200);
};
loader.setProgressFn(simulationFn);
}
And that’s it.
I’m not all that knowledgeable about Javascript, but this code, however inelegant, works.
I feel like this is a really late reply but I’m gonna try anyways.
Someone please help regarding this. I implemented the code given by Unforgiven above and now the page is just stuck on the loading screen with the logo and no progress. Maybe there is some fault in the code. I tried but nothing really helped. The code seems fine. Just that it isn’t detecting any progress.
Any help would be much appreciated!
That was really awesome. I was looking for a effect like this for my portfolio website. And my search came to an end. Thanks Mary
