Smooth Vertical or Horizontal Page Scrolling with jQuery

View demoDownload source

In this tutorial we will create a simple smooth scrolling effect with jQuery. We will create a horizontal and a vertical website layout to show the effect. We will be using the jQuery Easing Plugin and just a few lines of jQuery.

So, let’s start!

The Markup

The markup for our example page is going to be very plain. We will have three sections with a heading and a paragraph and am unordered list for the navigation:

<div class="section black" id="section1">
	<h2>Section 1</h2>
	<p>
		MY Spectre around me night and day
		Like a wild beast guards my way;
		My Emanation far within
		Weeps incessantly for my sin.
	</p>
	<ul class="nav">
		<li>1</li>
		<li><a href="#section2">2</a></li>
		<li><a href="#section3">3</a></li>
	</ul>
</div>
<div class="section white" id="section2">
	<h2>Section 2</h2>
	<p>
		A fathomless and boundless deep,
		There we wander, there we weep;
		On the hungry craving wind
		My Spectre follows thee behind.

	</p>
	<ul class="nav">
		<li><a href="#section1">1</a></li>
		<li>2</li>
		<li><a href="#section3">3</a></li>
	</ul>
</div>
<div class="section black" id="section3">
	<h2>Section 3</h2>
	<p>
		He scents thy footsteps in the snow
		Wheresoever thou dost go,
		Thro' the wintry hail and rain.
		When wilt thou return again?

	</p>
	<ul class="nav">
		<li><a href="#section1">1</a></li>
		<li><a href="#section2">2</a></li>
		<li>3</li>
	</ul>
</div>

The HTML is going to be the same for both examples.
Let’s take a look at the style.

The CSS

Since we have two examples, we will start with the horizontal page style.

The main idea is to make the sections very wide and 100% in height. We will add a background image to the bottom right of each section:

*{
    margin:0;
    padding:0;
}
body{
    background:#000;
    font-family:Georgia;
    font-size: 34px;
    font-style: italic;
    letter-spacing:-1px;
    width:12000px;
    position:absolute;
    top:0px;
    left:0px;
    bottom:0px;
}
.section{
    margin:0px;
    bottom:0px;
    width:4000px;
    float:left;
    height:100%;
    text-shadow:1px 1px 2px #f0f0f0;
}
.section h2{
    margin:50px 0px 30px 50px;
}
.section p{
    margin:20px 0px 0px 50px;
    width:600px;
}
.black{
    color:#fff;
    background:#000 url(../images/black.jpg) no-repeat top right;
}
.white{
    color:#000;
    background:#fff url(../images/white.jpg) no-repeat top right;
}
.section ul{
    list-style:none;
    margin:20px 0px 0px 550px;
}
.black ul li{
    float:left;
    padding:5px;
    margin:5px;
    color:#aaa;
}
.black ul li a{
    display:block;
    color:#f0f0f0;
}
.black ul li a:hover{
    text-decoration:none;
    color:#fff;
}
.white ul li{
    float:left;
    padding:5px;
    margin:5px;
    color:#aaa;
}
.white ul li a{
    display:block;
    color:#222;
}
.white ul li a:hover{
    text-decoration:none;
    color:#000;
}

We need to give the body a valid height, because we want to be able to define the height 100% to the section. With positioning the body absolutely and saying top:0px and bottom:0px we stretch the body and give it a height.

The style for the vertical page layout is going to look as follows:

*{
    margin:0;
    padding:0;
}
body{
    background:#000;
    font-family:Georgia;
    font-size: 34px;
    font-style: italic;
    letter-spacing:-1px;
}
.section{
    margin:0px;
    height:4000px;
    width:100%;
    float:left;
    text-shadow:1px 1px 2px #f0f0f0;
}
.section h2{
    margin:50px 0px 30px 50px;
}
.section p{
    margin:20px 0px 0px 50px;
    width:600px;
}
.black{
    color:#fff;
    background:#000 url(../images/black_vert.jpg) repeat-x bottom left;
}
.white{
    color:#000;
    background:#fff url(../images/white_vert.jpg) repeat-x bottom left;
}
.section ul{
    list-style:none;
    margin:20px 0px 0px 550px;
}
.black ul li{
    float:left;
    padding:5px;
    margin:5px;
    color:#aaa;
}
.black ul li a{
    display:block;
    color:#f0f0f0;
}
.black ul li a:hover{
    text-decoration:none;
    color:#fff;
}
.white ul li{
    float:left;
    padding:5px;
    margin:5px;
    color:#aaa;
}
.white ul li a{
    display:block;
    color:#222;
}
.white ul li a:hover{
    text-decoration:none;
    color:#000;
}

Nothing special here, just that we give a big height to the sections. The background image is positioned to the bottom left then.

Let’s add the JavaScript

The JavaScript

The function for the horizontal scrolling effect is the following:

$(function() {
	$('ul.nav a').bind('click',function(event){
		var $anchor = $(this);
		/*
		if you want to use one of the easing effects:
		$('html, body').stop().animate({
			scrollLeft: $($anchor.attr('href')).offset().left
		}, 1500,'easeInOutExpo');
		 */
		$('html, body').stop().animate({
			scrollLeft: $($anchor.attr('href')).offset().left
		}, 1000);
		event.preventDefault();
	});
});

And the function for the vertical scrolling effect is the following:

$(function() {
	$('ul.nav a').bind('click',function(event){
		var $anchor = $(this);

		$('html, body').stop().animate({
			scrollTop: $($anchor.attr('href')).offset().top
		}, 1500,'easeInOutExpo');
		/*
		if you don't want to use the easing effects:
		$('html, body').stop().animate({
			scrollTop: $($anchor.attr('href')).offset().top
		}, 1000);
		*/
		event.preventDefault();
	});
});

You can animate to the respective element by using one of the easing effects. You can see the effect in the vertical demo.
If there is no JavaScript enabled, we still have our good old scroll bars.

Check out the demo, it will lead you to the horizontal page. Here is the direct link to the demo of the vertical page scrolling, or simply click on the link in the horizontal demo.
