How to add a simple and responsive image gallery to Blogger (4 different styles)

This post will show you how to easily add a simple and responsive image gallery to your Blogger/Blogspot blog.

Galleries are a great way to display multiple images without making the user scroll through a long slow-loading page. This tutorial will show you how to add an image gallery in a grid layout with rows and columns.

You could use an image gallery to add a portfolio, project gallery, recipe gallery or a visual archive page that links to separate posts on your blog. You could also add a gallery within separate posts to showcase a collection of images such as travel photography, external products, shop this post or lookbook items.

How to add a simple and responsive image gallery to Blogger

On Blogger, go to Theme > Edit HTML and find the CSS section of your theme (between <b:skin> and ]]> </b:skin>). You’re going to add the CSS above the closing ]]> </b:skin> tag.

Style your image gallery with CSS

Paste the following right above ]]> </b:skin>

/* START SIMPLE RESPONSIVE GALLERY XOMISSE */
.gallery {
    padding: 0 5px;
    float: left;
    width: 24.99999%;
}

div.gallery img {
    width: 100%;
    height: auto;
}

div.gallery img:hover {
	opacity: 0.8;
}

div.desc {
    padding: 10px;
    text-align: center;
}

* {
    box-sizing: border-box;
}

@media only screen and (max-width: 700px){
    .gallery {
        width: 49.99999%;
        margin: 6px 0;
    }
}

@media only screen and (max-width: 500px){
    .gallery {
        width: 100%;
    }
}

.image-gallery:after {
    content: "";
    display: table;
    clear: both;
}
/* END SIMPLE RESPONSIVE GALLERY XOMISSE */

This styles the images and captions in a grid format, as well as making it responsive (go from 4 columns to 2 columns to 1 column depending on screen size). Customise this CSS as you wish.

Want a 3 column grid instead? Change the width value on .gallery to 33.333% instead.

Build your image gallery with HTML

There are four style options depending on if you want a standard image gallery with/without captions or a clickable gallery, with/without captions, that links to other posts, pages or external sites.

To add the gallery to a post, page or gadget, copy and paste the following HTML. It’s important that you make sure you’re pasting it in HTML mode (not compose/rich text mode) and don’t switch between modes once you paste it, otherwise Blogger will add code between the lines and break the structure.

<div class="image-gallery">

  <!-- Grid Image Gallery -->
  <div class="gallery">
      <img src="IMAGE-URL" alt="SEO-IMAGE-CAPTION">
  </div>

  <!-- Grid Image Gallery with Caption -->
  <div class="gallery">
      <img src="IMAGE-URL" alt="SEO-IMAGE-CAPTION">
      <div class="desc">DISPLAYED-CAPTION</div>
  </div>

  <!-- Clickable Grid Image Gallery -->
  <div class="gallery">
    <a href="LINK" target="_blank">
      <img src="IMAGE-URL" alt="SEO-IMAGE-CAPTION">
    </a>
  </div>

  <!-- Clickable Grid Image Gallery with Caption -->
  <div class="gallery">
    <a href="LINK" target="_blank">
      <img src="IMAGE-URL" alt="SEO-IMAGE-CAPTION">
    </a>
    <div class="desc">DISPLAYED-CAPTION</div>
  </div>

</div> 

Now upload your images and replace IMAGE-URL with the direct image URL.

Replace LINK with the post, page or external site you want that image to link to. Replace SEO-IMAGE-CAPTION and DISPLAYED-CAPTION with an SEO friendly descriptive caption.

To add more images, simply copy and paste the block of Grid Image code within the image-gallery div wrapper.

You can now save and publish your post or page. Your image gallery should be displayed in a nice grid and be responsive when you change the browser screen size.
