Before we begin, ensure you have a basic understanding of HTML, as CSS is used to style HTML elements. If you’re new to HTML, it’s advisable to learn the basics first.

Step 1: HTML Structure

First, let’s set up the HTML structure for our image gallery. Create an HTML file (e.g., index.html) and add the following code:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="styles.css">
    <title>CSS Image Gallery</title>
    <div class="gallery">
        <div class="gallery-item">
            <img src="image1.jpg" alt="Image 1">
        <div class="gallery-item">
            <img src="image2.jpg" alt="Image 2">
        <!-- Add more images as needed -->

This code sets up the basic HTML structure for our gallery, including links to an external CSS file (styles.css) where we’ll define our styles.

Step 2: CSS Styling:

Now, let’s style our image gallery. Create a CSS file (e.g., styles.css) and add the following CSS code:

/* Reset default margin and padding */
body, html {
    margin: 0;
    padding: 0;

/* Style the gallery container */
.gallery {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
    padding: 20px;

/* Style individual gallery items */
.gallery-item {
    width: calc(33.33% - 10px); /* 3 columns with spacing */
    margin-bottom: 20px;
    overflow: hidden;
    position: relative;

/* Style images within gallery items */
.gallery-item img {
    width: 100%;
    height: auto;
    display: block;
    transition: transform 0.2s;

/* Add a hover effect to images */
.gallery-item:hover img {
    transform: scale(1.1);

Here’s an explanation of the key CSS rules:

  • We reset default margin and padding to ensure a clean layout.
  • The .gallery class is set to display gallery items in a flexbox layout with spacing between them.
  • Each .gallery-item represents an image container with defined dimensions.
  • Images within .gallery-item are set to scale slightly when hovered, creating a zoom effect.

Step 3: Adding More Images:

To add more images to your gallery, simply duplicate the .gallery-item code within the <div class="gallery"> section in your HTML file and update the src and alt attributes for each image.

<div class="gallery-item">
    <img src="image3.jpg" alt="Image 3">
