Live Example: Simple Photo Gallery with CSS Grid

HTML Structure:

<div class="gallery">
  <div class="photo" style="background-image:url('photo1.jpg');"></div>
  <div class="photo" style="background-image:url('photo2.jpg');"></div>
  <div class="photo" style="background-image:url('photo3.jpg');"></div>
  <div class="photo" style="background-image:url('photo4.jpg');"></div>
  <div class="photo" style="background-image:url('photo5.jpg');"></div>
  <!-- Add more photos as needed -->
</div>

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

.photo {
  background-size: cover;
  background-position: center;
  height: 200px; /* Adjust based on preference */
}

Explanation:

The .gallery class is set to display: grid;, turning it into a grid container.
grid-template-columns: repeat(auto-fit, minmax(250px, 1fr)); creates a responsive grid where each column is at least 250px wide but can grow to fill available space (1fr). The auto-fit keyword adjusts the number of columns based on the container’s width, ensuring the gallery is responsive without the need for media queries.
grid-gap: 10px; adds space between grid items.
Each .photo div uses a background image for demonstration. Adjust the background-image URL to point to your photos.
background-size: cover; and background-position: center; ensure the photos cover the grid item area fully and are centered.

This example demonstrates how to use CSS Grid to create a responsive photo gallery. By adjusting the grid-template-columns property, you can easily customize the layout to suit different content types or design needs. CSS Grid’s power lies in its simplicity and flexibility, allowing for complex layouts with minimal code.
