What is parallax scrolling

Parallax scrolling, also known as “Asymmetrical scrolling”, is a technique in computer graphics and web design, where background images is moved at a different speed than the foreground content while scrolling, creating an illusion of depth in a 2D scene and adding to the immersion.

Below you can find the CSS and HTML on how to create parallax effect

* {
	box-sizing: border-box;
	margin: 0;
	padding: 0;
	font-family: lato;
	font-size: 16px;
	line-height: 24px;
.wrap {
	max-width: 980px;
	margin: 0 auto;
.noncont {
	padding: 50px 30px;
	font-size: 22px;
.noncont h3 {
	text-align: center;
	font-size: 30px;
	margin-bottom: 20px;
html {
	height: 100%;
.parallax {
	/* The image used */
	/* Set a specific height */
	min-height: 100%;
	/* Create the parallax scrolling effect */
	background-attachment: fixed;
	background-position: center;
	background-repeat: no-repeat;
	background-size: cover;
	position: relative;
.content {
	position: absolute;
	top: 50%;
	left: 50%;
	transform: translate(-50%, -50%);
	padding: 30px;
	background: rgba(0, 0, 0, 0.5);
	color: #fff;
.bot {
	bottom: 20px;
	top: auto;
.bgimg1 {
	background-image: url("cycle.jpg");
.bgimg2 {
	background-image: url("cycle2.jpg");
	min-height: 500px;
@keyframes transdown {
	0% {
		top: -5px;
	100% {
		top: 5px;
.dwnar {
	animation: transdown 800ms infinite alternate;
	position: relative;
	margin-top: -10px;

		<h3>What is parallax effect in web design?</h3>
		<p>One fairly recent web design trend is parallax scrolling, which involves the background moving at a slower rate to the foreground, creating a 3D effect as you scroll down the page. It can sometimes be overwhelming, but when used sparingly it can provide a nice, subtle element of depth.</p>

		<h3>What is parallax effect in web design?</h3>
		<p>The parallax effect has been around for years in classic video games, but it became a trend in the web design world. This cool effect is now commonly seen as part of the scrolling feature of a web page. It uses multiple backgrounds which seem to move at different speeds to create a sensation of depth (creating a faux-3D effect) and an interesting browsing experience. The term is derived from the Greek "parallaxis", meaning "alteration". Nearby objects have a larger parallax than more distant objects when observed from different positions, so parallax scrolling can be used to determine distances.</p>

Some mobile devices might have problem with “background-attachment: fixed”. However, you can use media queries to turn off the parallax effect for mobile devices by overriding with “background-attachment: scroll:.
You can adjust the height value of absolute positioned content in mobile devices using media queries.
