📸 HTML Image Gallery Tutorial for Beginners

Image galleries make your website more beautiful and professional. In this tutorial, you will learn how to create different types of image galleries using HTML and CSS.

📌 1. Simple HTML Image Gallery

This is the most basic gallery layout.

<div>
  <img src="image1.jpg" width="200">
  <img src="image2.jpg" width="200">
  <img src="image3.jpg" width="200">
</div>

✔ Explanation

All images are inside a <div>
Each image has the same width
They appear in a row

📌 2. Responsive Image Gallery (CSS Grid)

This gallery automatically adjusts on mobile and PC.

<style>
.gallery {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
  gap: 15px;
}
.gallery img {
  width: 100%;
  border-radius: 10px;
}
</style>

<div class="gallery">
  <img src="image1.jpg">
  <img src="image2.jpg">
  <img src="image3.jpg">
  <img src="image4.jpg">
</div>

✔ Why This Is Good

Fully responsive
Automatically adjusts number of columns
Perfect for modern websites

📌 3. Hover Effect Gallery

Add zoom effect on mouse hover.

<style>
.gallery img {
  width: 100%;
  border-radius: 10px;
  transition: 0.3s;
}
.gallery img:hover {
  transform: scale(1.05);
  box-shadow: 0 0 10px rgba(0,0,0,0.4);
}
</style>

<div class="gallery">
  <img src="img1.jpg">
  <img src="img2.jpg">
  <img src="img3.jpg">
</div>

📌 4. Image Gallery with Captions

Useful when you want to label images.

<style>
.gallery-item {
  text-align: center;
}
.gallery-item img {
  width: 100%;
  border-radius: 10px;
}
.caption {
  margin-top: 5px;
  font-weight: bold;
}
</style>

<div class="gallery">
  <div class="gallery-item">
    <img src="img1.jpg">
    <div class="caption">Beautiful Sunset</div>
  </div>

  <div class="gallery-item">
    <img src="img2.jpg">
    <div class="caption">Mountain View</div>
  </div>
</div>

📌 5. Click-to-Open Large Image (Lightbox)

Clicking an image opens a bigger view — without JavaScript!

<style>
.lightbox img {
  width: 100%;
  border-radius: 10px;
  cursor: pointer;
}
.lightbox:target {
  position: fixed;
  top: 0; left: 0;
  width: 100%; height: 100%;
  background: rgba(0,0,0,0.9);
  display: flex;
  justify-content: center;
  align-items: center;
}
.lightbox:target img {
  width: 90%;
  max-width: 600px;
}
</style>

<a href="#img1" class="thumb">
  <img src="photo1.jpg" width="200">
</a>

<div id="img1" class="lightbox">
  <a href="#">
    <img src="photo1.jpg">
  </a>
</div>
