Step 1: Understanding CSS

CSS, or Cascading Style Sheets, is a style sheet language used to control the presentation of web documents. CSS allows you to define the layout, colors, fonts, and other visual aspects of your web page. Before diving into Image Sprites, it’s essential to have a basic understanding of CSS syntax.

Sample CSS Code:

/* This is a CSS comment */
body {
    background-color: #f0f0f0;
    font-family: Arial, sans-serif;


  • CSS rules are written within curly braces {}.
  • Each rule consists of a selector (e.g., body) and a declaration block (e.g., { background-color: #f0f0f0; }).
  • Declarations set properties (e.g., background-color) and values (e.g., #f0f0f0) for selected elements.

Step 2: CSS Image Sprites Overview

CSS Image Sprites are a technique where multiple images are combined into a single image file. This single image is then used for different parts of a web page, reducing the number of HTTP requests and improving load times.

Step 3: Creating an Image Sprite

To create an Image Sprite, you need to combine multiple images into one. You can use tools like Photoshop or online sprite generators for this purpose.

Sample CSS for Image Sprite:

.sprite {
    background-image: url('sample-sprite.png');
    width: 100px;
    height: 100px;


  • .sprite is a CSS class that we’ll apply to HTML elements.
  • background-image sets the sprite image.
  • width and height specify the dimensions of individual images within the sprite.

Step 4: Using Image Sprites
Now that we have an Image Sprite, let’s use it in an HTML document.

Sample HTML Code:

<!DOCTYPE html>
    <link rel="stylesheet" type="text/css" href="styles.css">
    <h1>Image Sprite Example</h1>
    <div class="sprite"></div>


  • We link to our CSS file (styles.css) in the <head> section of the HTML document.
  • We create an HTML <div> element with the class .sprite to display the image from our sprite.

Step 5: Displaying Different Parts of the Sprite

To display different images from the sprite, you can use the background-position property.

Sample CSS for Different Image Sections:

.sprite {
    background-image: url('sample-sprite.png');
    width: 100px;
    height: 100px;

.sprite-image1 {
    background-position: 0 0; /* X and Y coordinates */

.sprite-image2 {
    background-position: -100px 0;


  • .sprite-image1 and .sprite-image2 are additional CSS classes.
  • background-position determines which part of the sprite to display.
