<p>A CSS image gallery allows you to display images in a clean, organized way. Using CSS, you can add styles, layout options, and even effects such as hover animations to make galleries more interactive.</p>

<h3>Example 1: Basic Image Grid Gallery</h3>
<p>This example demonstrates a simple image grid layout with CSS. Images are arranged in rows and columns, adapting to the screen size.</p>
<div class="contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative bg-token-sidebar-surface-primary dark:bg-gray-950">
<div class="flex items-center text-token-text-secondary px-4 py-2 text-xs font-sans justify-between rounded-t-md h-9 bg-token-sidebar-surface-primary dark:bg-token-main-surface-secondary">html</div>
<div class="sticky top-9 md:top-[5.75rem]">
<div class="absolute bottom-0 right-2 flex h-9 items-center">
<div class="flex items-center rounded bg-token-sidebar-surface-primary px-2 font-sans text-xs text-token-text-secondary dark:bg-token-main-surface-secondary">
<pre class="language-markup"><code>&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;
&lt;head&gt;
    &lt;meta charset="UTF-8"&gt;
    &lt;meta name="viewport" content="width=device-width, initial-scale=1.0"&gt;
    &lt;title&gt;Basic CSS Image Gallery&lt;/title&gt;
    &lt;style&gt;
        /* Gallery container */
        .gallery {
            display: grid;
            grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
            gap: 10px;
            padding: 10px;
        }

/* Gallery images */
        .gallery img {
            width: 100%;
            height: auto;
            display: block;
            border-radius: 8px;
            transition: transform 0.3s ease;
        }

/* Hover effect */
        .gallery img:hover {
            transform: scale(1.05);
        }
    &lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class="gallery"&gt;
        &lt;img src="https://via.placeholder.com/200" alt="Image 1"&gt;
        &lt;img src="https://via.placeholder.com/200" alt="Image 2"&gt;
        &lt;img src="https://via.placeholder.com/200" alt="Image 3"&gt;
        &lt;img src="https://via.placeholder.com/200" alt="Image 4"&gt;
        &lt;img src="https://via.placeholder.com/200" alt="Image 5"&gt;
        &lt;img src="https://via.placeholder.com/200" alt="Image 6"&gt;
    &lt;/div&gt;

&lt;/body&gt;
&lt;/html&gt;

<h4>Explanation:</h4>
<ul>
<li><strong><code>.gallery</code></strong>: Uses CSS Grid to create a responsive layout with images wrapping based on the screen size.</li>
<li><strong><code>.gallery img:hover</code></strong>: Slightly enlarges the image on hover, creating a zoom effect.</li>
</ul>
<hr />
<h3>Example 2: Lightbox Image Gallery</h3>
<p>This example includes a lightbox effect, where clicking an image enlarges it and dims the background.</p>
<div class="contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative bg-token-sidebar-surface-primary dark:bg-gray-950">

<div class="sticky top-9 md:top-[5.75rem]">
<div class="absolute bottom-0 right-2 flex h-9 items-center">
<div class="flex items-center rounded bg-token-sidebar-surface-primary px-2 font-sans text-xs text-token-text-secondary dark:bg-token-main-surface-secondary">

    &lt;title&gt;CSS Lightbox Image Gallery&lt;/title&gt;
    &lt;style&gt;
        /* Gallery styling */
        .gallery {
            display: flex;
            flex-wrap: wrap;
            gap: 10px;
            padding: 10px;
        }

/* Lightbox overlay */

    &lt;script&gt;
        function openLightbox(src) {
            const lightbox = document.querySelector('.lightbox');
            const lightboxImg = document.querySelector('.lightbox img');
            lightboxImg.src = src;
            lightbox.style.display = 'flex';
        }

function closeLightbox() {

<h4>Explanation:</h4>
<ul>
<li><strong><code>.lightbox</code></strong>: An overlay that appears over the gallery when an image is clicked. It contains an enlarged version of the clicked image.</li>
<li><strong>JavaScript functions</strong>: <code>openLightbox(src)</code> displays the clicked image in the lightbox, and <code>closeLightbox()</code> hides it when the overlay is clicked.</li>
