Basics of Image Gallery Structure

HTML Structure

Create a basic HTML structure for an image gallery.

				
					<div class="image-gallery">
  <div class="gallery-item">
    <img data-lazyloaded="1" src="data:image/gif;base64,R0lGODdhAQABAPAAAMPDwwAAACwAAAAAAQABAAACAkQBADs=" decoding="async" data-src="image1.jpg" alt="Image 1">
  </div>
  <div class="gallery-item">
    <img data-lazyloaded="1" src="data:image/gif;base64,R0lGODdhAQABAPAAAMPDwwAAACwAAAAAAQABAAACAkQBADs=" decoding="async" data-src="image2.jpg" alt="Image 2">
  </div>
  
</div>

Basic CSS Styling

Apply basic styling to structure the image gallery.

				
					.image-gallery {
  display: flex;
  flex-wrap: wrap;
}

.gallery-item {
  width: 33.33%; /* Set the width of each gallery item */
  box-sizing: border-box;
  padding: 10px;
}

.gallery-item img {
  width: 100%; /* Make images fill the container */
  border-radius: 8px; /* Add rounded corners to images */
}

Advanced Image Gallery Techniques

CSS Grid Layout

Utilize CSS Grid for a more flexible and responsive image gallery.

				
					.image-gallery {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
  gap: 10px;
}

Hover Effects

Add hover effects for a more interactive gallery.

				
					.gallery-item:hover {
  transform: scale(1.05); /* Scale up on hover */
  transition: transform 0.3s ease;
}

Lightbox Effect

Implement a lightbox effect for a better user experience.

				
					.lightbox {
  display: none;
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.9);
}

.lightbox img {
  max-width: 100%;
  max-height: 100%;
  display: block;
  margin: auto;
  box-shadow: 0 0 20px rgba(255, 255, 255, 0.5);
}

Examples

Masonry Layout

Create a masonry layout for a dynamic and visually interesting gallery.

				
					.image-gallery {
  column-count: 3;
  column-gap: 10px;
}

.gallery-item {
  break-inside: avoid;
  margin-bottom: 10px;
}

Caption Overlay

Add caption overlays to provide additional context to images.

				
					.caption-overlay {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  opacity: 0;
  transition: opacity 0.3s;
}

.gallery-item:hover .caption-overlay {
  opacity: 1;
  background: rgba(0, 0, 0, 0.7);
  color: #fff;
}
