You can replace the image URLs with your own or use placeholders like the ones shown here. Step 2: Style the Gallery With CSS Grid Now let’s apply grid layout styles to the container so the images arrange themselves cleanly across different screen sizes. .gallery { display: grid; grid-template-columns: repeat(auto-fit, minmax(150px, 1fr)); gap: 12px; padding: 20px; max-width: 1000px; margin: auto; } .gallery img { width: 100%; display: block; border-radius: 8px; object-fit: cover; } This setup ensures: Images stretch to fit their container The grid adapts to the screen size Spacing and alignment look clean at any width Step 3: Make It Look Even Better You can easily add hover effects, light/dark mode tweaks, or even a lightbox script later if you want interactivity. Here’s a quick hover effect: .gallery img:hover { transform: scale(1.03); transition: transform 0.2s ease-in-out; box-shadow: 0 2px 12px rgba(0, 0, 0, 0.2); } Conclusion You now have a flexible, elegant image gallery built entirely with CSS Grid and Flexbox principles.

Build a Responsive Image Gallery Using Flexbox and Grid

Looking for a clean, responsive image gallery for your portfolio or project? In this tutorial, we’ll walk through how to build one using just HTML and CSS — no JavaScript, no libraries, just layout magic. We'll combine the power of Flexbox for structure and CSS Grid for responsive image placement.

Step 1: Set Up the Basic HTML

We’ll start with a simple container and image elements. You can replace the image URLs with your own or use placeholders like the ones shown here.

Step 2: Style the Gallery With CSS Grid

Now let’s apply grid layout styles to the container so the images arrange themselves cleanly across different screen sizes.

.gallery {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(150px, 1fr));
  gap: 12px;
  padding: 20px;
  max-width: 1000px;
  margin: auto;
}

.gallery img {
  width: 100%;
  display: block;
  border-radius: 8px;
  object-fit: cover;
}

This setup ensures:

Images stretch to fit their container
The grid adapts to the screen size
Spacing and alignment look clean at any width

Step 3: Make It Look Even Better

You can easily add hover effects, light/dark mode tweaks, or even a lightbox script later if you want interactivity. Here’s a quick hover effect:

.gallery img:hover {
  transform: scale(1.03);
  transition: transform 0.2s ease-in-out;
  box-shadow: 0 2px 12px rgba(0, 0, 0, 0.2);
}

Conclusion

You now have a flexible, elegant image gallery built entirely with CSS Grid and Flexbox principles. This type of layout is ideal for showcasing portfolio pieces, product photos, or blog content blocks.
