CSS Image Gallery

Welcome to The Coding College! In this tutorial, we will explore how to create a visually appealing CSS Image Gallery. An image gallery is a collection of images displayed in a grid-like layout, often used in portfolios, e-commerce sites, or any website that showcases images.

Why Use CSS for Image Galleries?

CSS provides a lightweight and flexible way to design image galleries. With properties like flexbox, grid, and responsive techniques, you can create professional-looking galleries without relying on heavy JavaScript libraries.

Basic HTML Structure

Let’s start with the basic structure for an image gallery.

Example HTML:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>CSS Image Gallery</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div class="gallery">
        <div class="gallery-item"><img src="image1.jpg" alt="Gallery Image 1"></div>
        <div class="gallery-item"><img src="image2.jpg" alt="Gallery Image 2"></div>
        <div class="gallery-item"><img src="image3.jpg" alt="Gallery Image 3"></div>
        <div class="gallery-item"><img src="image4.jpg" alt="Gallery Image 4"></div>
        <div class="gallery-item"><img src="image5.jpg" alt="Gallery Image 5"></div>
    </div>
</body>
</html>

Styling the Image Gallery with CSS

Here, we’ll use CSS to create a beautiful, responsive image gallery.

Example CSS:

/* General Styles */
body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
    background-color: #f5f5f5;
}

/* Gallery Container */
.gallery {
    display: grid; /* Use CSS Grid for layout */
    grid-template-columns: repeat(auto-fit, minmax(150px, 1fr)); /* Flexible columns */
    gap: 10px; /* Spacing between items */
    padding: 20px;
    background-color: white;
    max-width: 1200px;
    margin: auto;
}

/* Gallery Items */
.gallery-item {
    overflow: hidden; /* Prevent images from overflowing */
    border-radius: 8px; /* Rounded corners */
    box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1); /* Subtle shadow */
    transition: transform 0.3s ease-in-out; /* Smooth scaling effect */
}

/* Gallery Images */
.gallery-item img {
    width: 100%; /* Make images responsive */
    height: auto; /* Maintain aspect ratio */
    display: block; /* Remove default gaps */
}

/* Hover Effect */
.gallery-item:hover {
    transform: scale(1.05); /* Slight zoom on hover */
}

Adding a Responsive Design

To ensure the gallery looks great on all devices, we’ll add media queries.

Example:

@media (max-width: 768px) {
    .gallery {
        grid-template-columns: repeat(auto-fit, minmax(100px, 1fr)); /* Smaller columns on mobile */
    }
}

Adding Captions to the Gallery

Enhance your gallery by adding captions below the images.

Example HTML:

<div class="gallery">
    <div class="gallery-item">
        <img src="image1.jpg" alt="Gallery Image 1">
        <p class="caption">Image 1 Description</p>
    </div>
    <div class="gallery-item">
        <img src="image2.jpg" alt="Gallery Image 2">
        <p class="caption">Image 2 Description</p>
    </div>
</div>

Example CSS:

.caption {
    text-align: center;
    font-size: 14px;
    color: #555;
    margin-top: 5px;
}

Creating a Lightbox Effect

For an interactive gallery, you can add a lightbox effect using CSS and minimal JavaScript. A lightbox displays an enlarged image when clicked.

Example HTML:

<div class="gallery">
    <div class="gallery-item">
        <img src="image1.jpg" alt="Gallery Image 1" onclick="openLightbox(this)">
    </div>
    <div id="lightbox" onclick="closeLightbox()">
        <img id="lightbox-img" src="" alt="">
    </div>
</div>

Example CSS:

/* Lightbox Styles */
#lightbox {
    display: none; /* Hidden by default */
    position: fixed; /* Fixed position */
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(0, 0, 0, 0.8); /* Dark overlay */
    justify-content: center;
    align-items: center;
}

#lightbox img {
    max-width: 90%;
    max-height: 90%;
    border-radius: 8px;
}

/* Show Lightbox */
#lightbox.show {
    display: flex; /* Flexbox for centering image */
    z-index: 10;
}

JavaScript:

function openLightbox(image) {
    const lightbox = document.getElementById('lightbox');
    const lightboxImg = document.getElementById('lightbox-img');
    lightboxImg.src = image.src;
    lightbox.classList.add('show');
}

function closeLightbox() {
    document.getElementById('lightbox').classList.remove('show');
}
