Background Parallax Webpage with CSS

parallax website CSS

Parallax scrolling is a technique where the background moves at a different speed than the foreground. Ideally, the effect has many layers: a background, a mid-ground, and a foreground. These layers moving at different speeds create the illusion of depth and immersion

  • The background layer forms the foundation of the parallax effect. It typically consists of large, visually captivating images or patterns that set the scene and establish the mood of the website.
  • The mid-ground layer serves as an intermediary between the background and foreground, providing additional visual interest and depth.
  • The foreground layer contains the primary content and interactive elements that users engage with directly.

My favorite example comes from the classic Sonic the Hedgehog game on the Sega Genesis. In that game, the background layer encompasses lush landscapes, while the intermediate layer consists of trees and obstacles that add depth to the scene. Sonic and collectibles represent the foreground layer, with Sonic’s speedy movements contrasting the slower-paced background and intermediate layers.

HTML & CSS Parallax Effect

We can use HTML and CSS to achieve a parallax scrolling effect by manipulating the position and properties of background images or layers.

HTML:

<div class="parallax-container">
  <div class="parallax-background"></div>
  <div class="content">
    <!-- Your content here -->
  </div>
</div>

CSS:

.parallax-container {
  position: relative;
  overflow-x: hidden;
  overflow-y: auto; /* Enable vertical scrolling */
  height: 100vh; /* Set the container height to full viewport height */
}

.parallax-background {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 200%; /* Adjust height to create a taller background for parallax effect */
  background-image: url('background.jpg');
  background-size: cover;
  background-position: center;
  z-index: -1; /* Ensure background is behind content */
}

.content {
  padding: 20px;
  /* Other styles for your content */
}

  1. The .parallax-container serves as the main container for the parallax effect. It has relative positioning to contain the absolutely positioned background layer.
  2. The .parallax-background div contains the background image. It’s absolutely positioned to cover the entire container and set behind the content with a negative z-index.
  3. Adjusting the height of .parallax-background to be taller than the container creates the parallax effect when the user scrolls.
  4. The .content div holds the content and is positioned over the parallax background.

My Background Webpage

A few years ago, I made a single webpage to describe my professional background and experience. I decided to use a parallax background effect for this page. You can visit it here.

I really love the way the main logo text initially seems to blend into the foreground but remains static as you scroll. Upon scrolling, you’ll observe that the top text remains fixed while the second line moves independently, creating a distinct visual effect. It feels unexpected. The contrasting image backgrounds creates a fun juxtaposition.

And, it’s all done with CSS (no JavaScript necessary). You can create a simple parallax effect by adjusting the positioning of background images or layers using CSS properties like background-position and background-attachment. This allows the background to move at a different rate than the foreground content as the user scrolls, creating the illusion of depth.

Here is the code that I used to build this example:

<!doctype html>
<html class="no-js" lang="en">
