A simple scrolling layout with fixed background images using background-attachment: fixed and a navigation. The page will scroll smoothly to the selected section.

The HTML

<div id="cbp-fbscroller" class="cbp-fbscroller">
	<nav>
		<a href="#fbsection1" class="cbp-fbcurrent">Section 1</a>
		<a href="#fbsection2">Section 2</a>
		<a href="#fbsection3">Section 3</a>
		<a href="#fbsection4">Section 4</a>
		<a href="#fbsection5">Section 5</a>
	</nav>
	<section id="fbsection1"></section>
	<section id="fbsection2"></section>
	<section id="fbsection3"></section>
	<section id="fbsection4"></section>
	<section id="fbsection5"></section>
</div>

The CSS

/* Set all parents to full height */
html, body, 
.container,
.cbp-fbscroller,
.cbp-fbscroller section { 
	height: 100%; 
}

/* The nav is fixed on the right side  and we center it by translating it 50% 
(we don't know it's height so we can't use the negative margin trick) */
.cbp-fbscroller > nav {
	position: fixed;
	z-index: 9999;
	right: 100px;
	top: 50%;
	-webkit-transform: translateY(-50%);
	-moz-transform: translateY(-50%);
	-ms-transform: translateY(-50%);
	transform: translateY(-50%);
}

.cbp-fbscroller > nav a {
	display: block;
	position: relative;
	color: transparent;
	height: 50px;
}

.cbp-fbscroller > nav a:after {
	content: '';
	position: absolute;
	width: 24px;
	height: 24px;
	border-radius: 50%;
	border: 4px solid #fff;
}

.cbp-fbscroller > nav a:hover:after {
	background: rgba(255,255,255,0.6);
}

.cbp-fbscroller > nav a.cbp-fbcurrent:after {
	background: #fff;
}

/* background-attachment does the trick */
.cbp-fbscroller section {
	position: relative;
	background-position: top center;
	background-repeat: no-repeat;
	background-size: cover;
	background-attachment: fixed;
}

#fbsection1 {
	background-image: url(../images/1.jpg);
}

#fbsection2 {
	background-image: url(../images/2.jpg);
}

#fbsection3 {
	background-image: url(../images/3.jpg);
}

#fbsection4 {
	background-image: url(../images/4.jpg);
}

#fbsection5 {
	background-image: url(../images/5.jpg);
}

    Hi, I came across your post while looking for a fixed background one page website & your tutorial is great! What I would like to know but have not come across yet is, how can we make the background totally static? meaning to say the bird background does not move as you scroll through & the other pages are maybe enclosed with a DIV that has a transparent background? I ask this as I am a beginner so forgive me if this answer is obvious.

    Thank you,
    Su

    Cool!

    is there a way to tweak the .js so that you wont see more than one section at a time?

  5. 6

    Would there be a way to achieve this effect using inline img tags instead of background images for each section? I can’t seem to find any examples out there at all. And wondering if its even possible.
